So... just when you thought it would be straight forward...
Ran the RV overnight with about a 5-6 A load, was expecting it to pull the batteries down about 10-15% overnight. In the morning, everything was still alive and well.
Now, I just went out the the RV, and everything was dark. The batteries had shut themselve down, and when activated were reading only 10.5 V. When I plugged in shore power, the main breaker trips in about 20 s. Its back on solar. with the breaker reset, with the shore power unplugged, and the Furrion solar controller saying its charging (blinking green), but the voltage at the battery terminals is still only ~11.4 V.
I'm stumped.
- Upgraded the stock 8555 inverter to a new WFCO WF-8955-AD-MBA auto sensing main board
- I got two 12 V 100 Ah Renogy LiFePO4, replaced the two Interstate lead acid batteries.
- Turned it all on, actived the two Renogy batteries (they had already seen the charge current and activiated)
