RE: 50 amp in a 30

Hi Valhala360, That's a nice write up on hybrid inverter/chargers. However, do please realize that it is not "voltage support" (a la autoformer). It is possible to limit the incoming amperage. Since I'm 30 amp, I limit at 24. If I'm boondocking, I drop that to 12. If load support is active and the batteries drop too low, then the shore power breaker will trip. DAMHIK. After this summer, I'll be moving to a 7.2 KWH usable capacity battery bank. In the days before I had load support, I would do double conversion--plugging in only the converter--and running the RV from a 2500 watt inverter, powered by the 875 amp-hour (3.2 kwh usable) battery bank.

RE: LFP on Shore Power with Inverter/charger?

Why not just write the seller/maker? Who is the most 'senior' user of Li here? (i.e. longest use)

RE: Solar Panel Height

Mine are as close as possible given a curved roof. If I redo the system in summer of 2022, I'll have a rack that is above the air conditioner.

RE: 50 amp in a 30

Plan on running 24 amps (2880 watts), not 30. Monitor the voltage. I use load support from my inverter charger.

RE: 50amp EMS w/surge

Use a dog bone 30 to 50 adapter before the EMS. All will be well.

RE: Inverter

Do you mean the unit that charges the battery bank? If so, while your terminology is correct--in "trailer speak" they are called converters.

RE: image on phone

2oldman, I would keep the security running. Its not perfect--but it is better than running naked.

RE: effects of / protection from undervoltage

Hi, I do monitor a kill-a-watt meter and use a watt meter, too. I use a Sola Basic autoformer to which I have added external surge protection. I have experienced surge--but far more often low voltage. I tweaked the autoformer to cut in at 113 volts. (factory was 110) It has 3 layers of boost and one of buck. Hughes makes a nice autoformer with more bells and whistles than I have. I do combine the autoformer with the load support on the Magnum inverter/charger. Since I have a more than average size battery bank, this gives me superior results to some ems devices. My air conditioner is much happier at my brother's cottage where line voltage is always on the low side. So are my inductive devices, when I use the autoformer. While low voltage generally doesn't harm resistance devices--be aware that the usable power changes by the square of the voltage. For example: 107 x 107 = 11,449 122 x 122 = 14,884 11449 / 14884 =~76.9% or about a 23% lost of wattage.

RE: is a surge protector necessary for a basic travel trailer?

I have seen 100 volts NOT under load. I regularly use an autoformer and have tweaked it to "cut in" about 113 volts. My heaters produce more wattage, and the motor devices such as the air condtioner are much happier. On the above mentioned 100 volts, I was able to safely run my air conditioner, but it did eventually trip the shore breaker.

RE: 30 amps for 50 amp trailer

My RV is 30 amp--however I added two additional shore power cords. I use plugs so I can run the converter separately--then run the RV off the inverter. I use plugs on the water heater, too. The same could be done for a 2nd air conditioner. This gets around the gfci problem. This modification allows me a continuous load of 5400 watts, with a peak load of 7300 watts. That, in turn, allows me to heat 100% electrically at -37 c (-34 f). It's great for places where there are multiple 15 amp outlets on separate breakers. Combining it with a hybrid load support inverter/charger means I can run lots of items.

RE: BAttery replacement.

If the bank is meeting your needs why replace it?

RE: Multimeter Question

Checking voltage under load may be a good plan.

RE: Multimeter Question

get a kill-a-watt meter. get a hockey puck adapter. For 50 amp use a break out box.

RE: solar

Hi Jack, Here is a plain English series of articles on solar. https://freecampsites.net/adding-solar/ Start with an energy audit.

RE: is a surge protector necessary for a basic travel trailer?

Get an energy management system.

understanding battery discharge rates

RE: Battery price question...

Gdetrailer, All you have said is correct--but the REAL difference is that two six volts in series have 6 cells and two twelve volts in parallel have 12 cells. So the load per cell is 50% less with a pair of 12 volt cells. There are other factors too.

RE: Is my inverter fried?

Disconnect from DC power. Cycle the inverter on and then off. Wait ten minutes. Reconnect DC power. Turn on the inverter (after pouring a libation to the inverter gods).
