Re: PIP-5048MS inverter

Hi all, what setting controls the 04 low battery warning. My 5048ms is triggering at 49.5 v , which is not low for my 15s lfp batteries. TIA Robert Hi Robert. The low battery warning thresholds depend on the Low Cutoff Voltage (setting 29). In the standard firmware, a low battery warning is given a...

Re: PIP-4048MS inverter

There are several commands I don't recognise, such as QBEQI and PBEQA, which I think may be Query Battery EQualise Inquiry and Program Battery EQualisation Active respectively. But that's just a guess. Why guess when you can google it? See http://forums.aeva.asn.au/download/file.php?mode=view&id=64...

Re: PIP-4048MS inverter

Welcome @gbeppe

I'm guessing you have not set the battery type to "user", either by using the LCD and buttons to set parameter [5] to "USE" or "uSr", or by sending a serial command PBT02 with a CRC of 0x074C.

Weber, the battery voltage at 50.5 PV at 51.5, charging at 35 amps atm. That sure sounds like MOSFETs failed short-circuit in the SCC. The PV voltage wouldn't normally be so close to the battery voltage if it was maximum-power-point tracking, unless you only have 2 x 60 cell panels [Edit: in series...

Re: PIP-4048MS inverter

Assuming it charges just fine from AC alone, here's one hypothesis: A switching device in the SCC has failed short-circuit, so that the PV array is connected directly to the battery. In this case, you would expect the PV input voltage (which can be viewed on the LCD) to be only a fraction of a volt ...
