Hello. I have an Easysolar 12/1600/70 which is connected to 480AH of LiFePO4 batteries and 1100W of solar panels. (The system also has a Smartsolar 100/30, but that is not relevant to this question.) I have the equipment installed in my RV, which has a small front-loading washing machine in it (Dometic WMD 1050.). The washing machine will not run successfully on the inverter, no matter what I try, yet the same washing machine will run successfully using a Honda eu10i (1 KVA) inverter generator. Curiously, if I plug the generator into the RV and use the Easysolar inverter in power assist mode, the washing machine will not run, but it runs fine if connected directly to the generator.
The symptoms are: The washing machine will power up. A program cycle that does not use the water heating element can be selected. The machine can be started and the water solenoid will open and allow the washing machine to fill. During this process the bowl of the washing machine rotates slowly, as it is intended to do. Once filled, the machine switches to the wash cycle and the motor attempts to rotate the bowl, but it only rotates about 1/4 of a turn and stops. It repeats this process endlessly. When connected to the generator, at this point in the process, the bowl rotates correctly.
I get no alarms of any sort from the Easysolar 12/1600/70. No low voltage alarms (I have set the input DC low voltage cut-out to as low as it will go) are recorded on the alarm list.
Before I installed the Easysolar, I had a cheap Chinese-made 1000W, pure sine wave inverter and it would run the same washing machine with ease. This is very frustrating as I have invested a lot of money into the Easysolar, BMV, Colour control GX, etc and it is not performing a fairly straightforward function. The same inverter will run an electric toaster and my wife's hair-dryer, both of which are rated rated at 1200W, without any trouble. I am assuming that the inverter does not like the inductive load, or the 240VAC waveform of the inverter is not good enough for the washing machine when under load.
Can you suggest any settings that I may have wrong, that are preventing the washing machine from working?
