RE: AC question

Hi, items needed to do this: a large battery bank a 3000 watt hybrid inverter a 2000 watt generator If you need to use the air conditioner it is far cheaper to go to an inexpensive campground than to power it with the generator. Is it possible to use an ac unit with the 12v battery that comes with a trailer? If so why buy a big generator to run it? Could you not just run it with the dc current and the hook a smaller generator to the battery to keep it charged? thank you in advance for enlightening my ignorance.

RE: Connecting inverter to shore power cord

My converter plugs into the breaker box. That made life easy for disconnection. Will find the wire this weekend and go from there.

RE: Fridge - works on AC but is 'weak'

Replace the electric heater with one that draws more watts.

RE: Propane fridge -- how many watts per day on propane?

Hi, Duty cycle is about 2:3 therefore about 1 amp per hour X 24 hours = 24 amp-hours X 12 volts = 288 watt-hours. There are other parasitic loads, so the 'rule of thumb' is about 35 amp-hours per day. Solar is a nice way to treat your battery bank and it may reward you with a long service life.

RE: Charging Battery More Efficiently

Hi Mex, It will do 125 amps from a 15 amp shore power. I do not know about the time settings. I did not note the voltage. I do know you can 'dial back' the input amperage.

RE: Charging Battery More Efficiently

Hi Mex, The new hybrid magnum 3000 watt inverter charger has the features you are mentioning, if the remote control is used.

RE: Charging Battery More Efficiently

By far the most expensive way to charge batteries is using a generator, so using an appropriate voltage to get as many amps into the bank as quickly as possible is the goal. At a pedestal, multi stage or 13.2 volts both work well. AGM have a different charging profile, depending on the maker. They generally have much lower internal resistance. It is best to follow the maker's recommendations. So you Mxxxxxxxx guys just charge at one voltage, 14.8 or whatever? No multistage? Or do you use a multistage charger when you are plugged into a pedestal once in a while? And is this different for AGM?

RE: Will this solar system suffice?

Hi, The inverter is going to dwarf all the other loads. Count on at least 50 amp-hours per day for it. Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems! solar spreadsheet by N8GS 4. Inverter to charge my computer, cell phone, cameras about 4-5 hrs/day.

RE: Medical claim Denied

Hi, Anything that is life threatening is dealt with in a timely manner. Wait lists do exist, but they exist in USA, too. Unlike USA, we have the freedom to go to any facility in our Province. The supplemental insurance is a night mare, which gets worse the older you become. They are for emergency care only. As soon as the patient can travel they come back to Canada. My out of pocket cost for a broken leg in Canada was $60. In USA the average cost is $17,000.00. Given the long waits for some procedures that I hear exist in the Canadian Heath system, if the policies didn't exclude them, people would just buy a supplemental policy and come to the states for instant surgeries and care. Somewhere in the back of my pea-brain I hear an alarm going off that your friends aren't exactly telling you the truth, the whole truth, and nothing but the truth regarding what exactly they knew about their health condition before they went to Texas.

RE: Electrical - High Voltage

Hi Drew, Here is a page with details: http://www.hammondpowersolutions.com I suspect there are not two taps, but rather that 32V boost comes if you use it in a 240V circuit and 16V in a 120V circuit. By the way, I suspect the barn is well over 40 years old. A subpanel in the mid 70's would not typically have screw-in fuses, and a large barn built at that time likely would have had more than a 30A 240V service installed. (At least in this part of the country, an old barn is more like 100 or 150 years old and built with post-and-beam construction.)

RE: Electrical - High Voltage

Hi, Do you know if the QC50ESCB is wired in as an autotransformer?

RE: Adding House Battery

It is not best practise, but it will work and give you more capacity.

RE: Battery Voltage drop under load

Hi, The load will be closer to 26 amps due to inverter overhead. The thicker plates do cause greater voltage drop. Is a voltage drop to 12.0V to be expected with a 21.3A load with a fully charged ~216Ah battery bank? I've never loaded the batteries that much before, so really have no idea what to expect. It's a pair of 3 year old GCs, ~216Ah new, maintained by solar: daily charging up to 14.8V then 13.1V float. Haven't checked their sp.gr. recently but it was ok 6 months ago. When resting at 13.1 float, I turned on the newly installed inverter and then the frig (256W according to the inverter, so 21.3A at 12V), and the voltage at the batteries dropped to 12.0V. Turning off the frig, the battery voltage went quickly back up to 12.5V or so, and the solar controller was then in mppt.

RE: Low cost rear electric jacks on my Class B/C

What a great mod to make. Yes let us see them please.

RE: why don't Solar controller mfg/sellers use honest ratings

Hi Mr Wizard, I prefer discreet devices, too, but 999 for a 3000 watt psw inverter is pretty good and having the ability to do 30 amps of solar is a definite bonus.
pianotuna 06/27/15 03:39pm Tech Issues
mean well combo unit

psw inverter, charger, and solar controller, too! 30 amps of solar input

RE: why don't Solar controller mfg/sellers use honest ratings

This looks interesting--a combo inverter/charger/solar controller. inverter charger and solar controller It can accept 30 amps on the solar side.

RE: Electrical - High Voltage

Hi, The electrician did not put in wire with a sufficient thickness. I think you mean volts not amps. Replace the booster with a Hughes Autoformer. What make of booster was installed.

RE: Installed 1500 Watt Inverter And POP

Hi Bob, Many msw inverters give a false voltage reading. My 1000 watt inverter puts out 130 volts. When I saw that I do not plug anything into it...I do not know if it would drop down to 120 volts with a load attached or not....
