RE: Switching surge guard brands

Any MADE IN AMERICA proviso needs to say 100% Made in America with American components using American Workers. All a component needs is to be FINAL ASSEMBLED in America in order to qualify for the MADE IN AMERICA LABEL. Slage Lock. Made in a NAFTA trade zone (Tecate Mexico) using CHINESE components plasters the made in USA moniker across it's adsUSA cars made with Canadian sheet metal, Mexican cast and machined iron parts, Oriental manufactured electronics, yet it is proudly advertised as Made In USAMegawatt power supplies. Everything is Chinese except for the main circuit board which is machined and traced in Texas. Beware of Washington DC proclamations. When failed lawyers open their mouth...

RE: Oversize Image What A REAL Battery Charge Control Looks Like

Megawatt has a very large adjustable voltage power supply that can maintain 13.6 up to 14.1 volts good for power pedestal princesses.

RE: 1000 watt Yamaha generator?

Reset the Megawatt pot to 13.6 volts. Connect it at home and guess what...it will support a 30-amp FLOAT charge. Enter and leave the rig. Turn lights on. The batteries never cycle. They remain floating. A psychotic converter does not go through stupid cycling programs. How idiot programmers managed to make this stuff difficult is beyond me. David .... of course I accomplish the same thing whenever the RV is in storage at home by merely running an extension cord out to it and then letting it's good old Parallax 45 amp fixed voltage (~13.8 volts) stock converter FLOAT it's AGM batteries. But as you know, I bought AGM batteries (the liquid acid stock batteries were shot) that were specified to be floated at 13.5 to13-8 volts ... so that I wouldn't have to throw away and replace a perfectly good (and new) Parallax 7345 converter ... or buy a separate power supply for floating. Waste Not Want Not by maximizing what one already has in hand: However I agree that the Mega Watt is not much money to spend for keeping life in a K.I.S.S. mode ... assuming the power supply is going to last for years. BTW, my immaculate condition start-on-first-pull EX650 watt four stroke Honda generator was given to me around 30 years ago and is still going strong - but I probably should maximize use of it better going forward. My current approach of using my old Sears 2-10-50 charger in parallel with the RV's stock Parallax converter is a long way from what the Mega Watt model in your photo would do to enhance utilization of my little Honda!

RE: 1000 watt Yamaha generator?

I really try and quintuple check my relayed facts and figures. The baby Megawatt is a winner. The case is aluminum. With a SHARP pair of diagonal cutting pliers, chop the sheet metal bridges around the edge of the fan hole. Leaves a wide open hole with sorta ugly chopped off tabs that the dikes bit through. Buy an 80 mm wire fan guard and a tube of GOOP online. Dollop the four screw hole loops in the wire fan guard the then flop the fan guard on the hole (it hides the ugly chopped segments) Then proceed with the GOOP to glue the AC power in terminals, and the positive and negative battery cable screws on the terminal block. The hogged out fan opening allows for a simply tremendous increase in airflow. And the modification takes what...five minutes from start to finish? Don't forget to GOOP four rubber erasers (the big guys) to the bottom of the case. Most of the air inlet is blocked if you flop the bare Megawatt on it's belly. Now for the fun part. Crank er up set at 14.8 volts. See how long it takes to charge a battery in comparison to an Art Deco undercharger. Try it with a tiny generator. How many buttons do you NOT have to press? Plugger-in and wait till the batteries start bubbling. Kill the generator. Life does not have to be difficult and wasting money on fuel, patience and batteries is not supposed be be part of the program. Ooooooo lookie. Reset the Megawatt pot to 13.6 volts. Connect it at home and guess what...it will support a 30-amp FLOAT charge. Enter and leave the rig. Turn lights on. The batteries never cycle. They remain floating. A psychotic converter does not go through stupid cycling programs. How idiot programmers managed to make this stuff difficult is beyond me.

RE: 1000 watt Yamaha generator?

40 will kill the Yamaha dead. SG the rhetoric is to add a bit of humor. A voltmeter and a tiny screwdriver is standard operating procedure by Dalia by 12-year old granddaughter. Setting voltage a single time should not be taxing to an average adult. I purposely left out instructions so if any of the hundreds of people OTHER than the OP are interested I can go images on email. I wasn't joking about the time difference. Jesus' uncle told him the 55 dollar Megawatt couldn't POSSIBLY be as good as the hundred thirty nine dollar Dyson . Four hours later Jesus unplugged the B&D and finished charging (40 minutes) his LTH group 31 cyclable. Wanna know his quote? "I haven't got time for this". He pops the cell caps off and wanders over every half hour and sees if the cells are bubbling. He is no longer getting a year's use out of the LTH. But is on his third year. The battery is for his 24' panga with 60 HP Yamaha. He night dives and has LED lighting onboard lit always for his dive compressor. Now he is on generator power after the hurricane. The LTH is fully charged. But the little generator can only support the six foot wide freezer load. BFL13, thank you sir for alerting me to the ramped start-up charging of the B&D. I wasted over four hundred dollars on B&D chargers 2004 - 2007. They blew out the finals and being embedded with wave soldering were not fixable. And they did not charge worth snot. They ended up turning off at the 1.245 - 1.260 level. By today's standards paying almost four hundred dollars when a single hundred twenty dollar battery would work fine throughout the span of time, is absurd and an insult to my intelligence. My battery duties are not overnight wonders -- they get cycled and I mean cycled hard. I am in the middle of doing a capacity test of a seven year old Lifeline. Oooooo lookie, so far it is showing 100.0% capacity retention. Think its a fluke? I 2.666 vdc equalized the Rolls weak sister over the weekend and suddenly it isn't a weak sister. It equalized for 22 hours. Not bad for a battery that was installed when Monica Lewinski was in the headlines. But I admit - some people have A LOT more money for early battery failures than I do. Yes I am fussy about how things work. I do not like nine hundred dollar automatic dishwashers that need to have the plates removed and scrubbed after wasting a dollar's worth of electricity, either. Give me a diagram of how they should be hooked up, without damage to the trailer, and I do enjoy a challenge. I do have a 2000 watt inverter in my front storage area also, if that would help. I did not set up that, it came that way. I really don't understand that completely either, but haven't had it long. I have set up a few solar units on my various trailers. Mike

RE: 1000 watt Yamaha generator?

Yep "settle for something that stalls the Yamaha or never charges the battery". I verified what I recommended using a Harbor Fright 800 watt generator. THAT is the kicker some of you seem to be blind to. He has LESS wattage producing potential than you folks do. Those highly freaked B&D chargers have inrush. Have you challenged a thousand watt generator with one of the Black and Decker chargers? I seemed to have screwed-up and done exactly that and have instantly stalled the generator. The Megawatt doesn't. Or of course one could choose a 15 and not a thirty amp charge rate and set the alarm clock for 2:00 AM Sheeze No one is suggesting the Meanwell isn't a good choice, only pointing out the fact that this is a manually adjusted charger that may not be suitable for use by the OP who by his own admission has little understanding of electrical issues. You'd do much better to make your arguments in rational terms that everyone can understand and avoid the rhetoric that few do. :W Sheeze indeed. :R

RE: 1000 watt Yamaha generator?

Dangit!This is a BATTERY CHARGER You know -- something that is used ONLY with the Yamaha 1000 generator. Something that is loose. With battery cables with clips And a power cord with prongs. Now run down to Wally-China and see how much a Dack & Blecker Dyson vacuum cleaner look a like SMART charger costs. The Megawatt is a lot cheaper Unlike the Dyson style snot rag this thing will charge batteries fast and easy. The Dyson clone will flash lights, sulfate batteries. And waste time and fuel. A battery charger is SNOT a converter. Just like your Sure Flo water pump is not a bilge pump. Or the fresh water tank is not the black water tank. Convinced any Smart Battery Charger on the face of the earth can equal time needed to recharge a battery -- using a Yamaha 1000 generator? Bring money. The Megawatt set at 14.8 volts will recharge 30% faster and it CAN NOT overload the small generator. Not even counting current inrush. The CONTROL for this is automatic. No, not just the voltage setting, a running generator is damned difficult to forget about. Small generators run out of gas after just a few hours. Automatic function is referred to as INTRINSIC. So this setup has an INTRINSIC safety control that cannot be over-ridden unless a larger fuel tank is used. Wanna use it at home? Buy an inline timer switch for the AC power cord. This little guy will kick the living snot out of Art Deco Jerry Brown grade battery destroyers. But then there are some who insist on plugger-in-push-a-button and settle for whatever happens. Curiously enough -- these folks are happy with microwave TV dinners and virtual reality entertainment. I take the sides of the WALLET, and the BATTERY. Minimum generator run time. Minimum wallet bleed at the gas station, and minimum mileage trying to collect on a battery ruined by the customer. This setup is about as SIMPLE as it gets, unlike rationalized simplicity that deserves a rhino dart for irrational calculation. It's all about GENERATOR RUN TIME and the fact that only HOMER SIMPSON would forget about a running generator.

RE: Generator finally repaired after seven months

Few manufacturers have angered (different than disgusted) me than Onan. I have written in this forum about experiences with larger Onan generators from back in the eighties. When an off grid customer begged me to repair a one Megawatt Cummins Onan in the mid eighties that had parts backodered for months, I dove into it and was amazed at the purposely proprietary control circuitry with insane pricetags. An $1,100 voltage regulator that demanded current transformers. I counted eleven current transformers and absurdly complicated control and monitoring circuits. I measured the basics. Field resistance, amperage and voltage. Although it took an extremely expensive Delco H-10 model voltage regulator to mate with high field current, it could be done. I replaced instrumentation and governing devices with Simpson, Woodward, and Murphey gauges I ended up with a hundred pounds or more of scrap garbage. I even modified the secondary field with double-rated stud rectifiers (volts + amps) The unit went online and ran flawlessly six months of the year for as long as "Neal" owned the resort. "It has -never- since new ran problem free like this, and -never- has controlled voltage like your modifications have done" Onan, controls the RV aftermarket industry and has dominated military generator purchases for many decades. It wasn't just the arrogant stand-offishness I had to deal with, when the Onan rep discovered I had trashed a thirty thousand dollar repair job, they filed suit against me in superior court. When I sent them a packet of information listing my qualifications including being an expert witness county of Los Angeles, they lost interest. Fast. Good news for me, litigation would have lasted years. I would have gone for the jugular. And lost my butt in the end. To have a congressional investigation of the complex relationship between Onan and the US military would gladden my heart. So when I read stories like Mr. Bishop's my response is "Why Am I Not Surprised?" I laugh at the thought of Onan becoming angered at my public thrashing of their arrogance -- send a process server down here. Recommended attire -- polyester over Kevlar. My recommendation: If given a choice, avoid Onan like the bubonic plague.

RE: Deep cycle battery charger

Asked another way. Set voltage to say 14.45 When batteries are fully charged does the voltage read 14.45 or less? If less, how much less. There is a .15 volt discrepancy with power supplies. Let's say I fire up a Meanwell or a Megawatt and set voltage to 14.45 and the battery is right at fully charged to begin with. The voltage drops to 14.30 and stays there. The power supply can stay connected for a month and maintain 14.30. Disconnect the battery and it will rise to 14.45 <50mv ripple should answer that question. This is called "slump" and it's important enough to ask if it exists. Thank you.

RE: Fun To Look Back At Prices

Ferrocarriles Nacional stated a couple of times in the last ten years that any thought of carrying rigs on flat cars is "absolutely off the table". For laughs I priced shipping a car by freighter from Ensenada to Salina Cruz. Three weeks minimum. No passengers $4,200 dollars NOT including loading and unloading. No damage insurance. Then Aduana demands an existing valid TIP. Mexico's ferries are flat bottom Black Sea Danish hand-me-downs. In any sort of sea they ride like an LST with the aft end corskscrewing and bow slamming. Mexico sez Pemex is holding down the price of DIESEL MARINA, but we'll have to wait and see. Almost all rural grids are powered by ancient railroad locomotive engines pushing one megawatt generators. Looking for what Conasupo morphed into after ten transitional phases? TIENDAS DICONSAS Franchise markets with apoyo (help) with taxes and utilities and mass buying prices from proveedores (warehouses). CABINA ESPECIAL. Up toward the bow.

AGM Battery Charging THE PRIME DIRECTIVE

I have gotten several communications about AGM battery maintenance. Using solar voltaic charging. The big error I read is that the subject of total and complete recharging is not mentioned. And that is the # 1 most important mandatory requirement in AGM management. If panels cannot do it and your electricity charger cannot do it you are condemning the battery. The battery must be subjected to enough power to allow resistance to rise so that applying 14.4 volts across the battery... One group 24 battery allows .4 AMP or less into the battery Group 27 or 31 .5 amp GC220 1.1 amp Multiple batteries? Add each additional battery. Four golf car batteries -- 480 amp hour total = 2.2 amps maximum at 14.4 volts Forget amo hour counting, slide rules or hocus pocus -- one half amp per hundred ampere hours at 14.4 volts. That's the battery's law not mine. And this is a CHEMICAL matter, so time spent discharge is critical. Cycled to 50% every day is not as significant as cycling to 50% and then allowing the battery to remain at 50% level for days on end. The CLOSER you can recover to that 1/2% flow of amperage the longer you can go without actually reaching the half percent at 14.4. The deeper the discharge the more critical it becomes It's exactly like radiation dosage. Accumulation is far more important than intensity or time. Only in this case it is depth of discharge and time spent at depth. A battery that is discharged to only 70% total capacity and then spending many weeks at that level is affected every bit as much as a battery that is discharged to 40% state of charge for 10 days. But no matter what getting the battery at 14.4 volts and one half of one percent amp hour capacity amperage flow is key. A measly 400 watt megawatt power supply can take over when your converter falls flat on it's face delivering less than 35 amps and the megawatt which is set a 14.4 volts will finish the job.

RE: Battery Equilization PS Current Requirement

FIVE amps REGULATED AMPS. From starting voltage to 16.0 Volts 5.0 exact amps. Any other recipe is bogus. You need a power supply that reaches to SIXTEEN volts while maintaining exactly five amperes. The 26 amp Megawatt will go to 15.85 volts which is close enough. If you request it in advance, the Megawatt power supplies can be "built" to output 16.1V (at slightly lower than their rated current). An auto parts store FIFTY WATT trouble light 12 volt bulb will throttle amperage close enough to 5.0 amps as to be good enough. Placing a light bulb or suitable fixed resistor IN SERIES with the load, if an EXCELLENT way of current limiting any power supply that does NOT have current control. What you really want is a 3.1ohm - 3.5ohm resistor rated at about 75W. (Three 10ohm 25W resistors in parallel would be good.) If you are going to use a non-automatic charger (which is actually better in some ways), buy a cheap digital voltage/current meter from eBay.
