We have a small 19’ rv that we are converting to Solar/lithium. I am looking to find the most suitable Inverter for the upgrade. Here are some of the requirements..
1.] We would like to use two Leaf cells or two tesla Model S Batteries to create the battery bank
2.] We will only only have about 600 watts of solar that our rig can support as don’t want to be transporting any portable panels. When boon docking we calculate that over several days we will gradually draw down the batteries before needing the generator.
3.] The solar charge controller and the batteries are located together. About 15’ on the other side of the RV is the inverter which is housed near where the shore power comes in. There is 6ga wire to connect the inverter to the battery bank, so I would like to use 24v maybe even 48v so I don’t have to rewire
4.] for shore power we have a 30 amp connector near the inverter and are limited to a 2000 watt generator when boondocking. Otherwise we get a full 30 amp when connected to shore power. We need to be able to limit the charging from the generator as we don’t want to overload it when charging our batteries.
5.] The inverter needs to be able to draw from the batteries in cases where the generator is providing less than spikes for Air conditioner etc. , in our case we have about a 3k watt requirements in the RV max.
The inverter should be as small and light as possible I was thinking the Multiplus-II, but am not sure if the grid features would necessary, are there any other options I should consider?
