New to the game and just had my RV fitted with lithium batteries (400Ah), additional solar panels (600W total) and a BMV-712. The BMV-712 shows a 2.8A load with the battery cut-off switch enabled. After 6 days, the SOC was showing 6% (no use, RV sitting outside in the California sun, battery disconnect set to off) and the voltage showed 14.2.
I discovered the "Zero Current Calibration" procedure in the manual, and have yet to perform it as the trailer is still in storage. But that made me wonder:
- Is the SOC reading affected by the potentially inaccurate 3A draw reading, and the batteries themselves are (near) fully charged?
- If SOC really is 6%, wouldn't the batteries show something less that 14.2V?
I enjoy learning about these things, but admittedly, am just starting out with Lithium/Solar/Victron. Thanks in advance for any advice.
