Re: PIP-4048MS and PIP-5048MS inverters

was bidirectional. To sort out what really happens with a low battery voltage, Weber kindly reconfigured his battery from 16S of LFP (nominally 51.2 V) to 13S (nominally 41.6 V).His 64 V model inverter claimed it was generating 230 Vac on the LC Display. With the battery voltage at 44.4 V, the bus ...

Re: PIP-4048MS and PIP-5048MS inverters

I think the biggest hassle would be that the firmware will treat the battery as "weak" (with several implications, including a low battery warning and switching to bypass mode if possible) when the battery voltage drops to below 42.0 V (2.0 V above the low DC cutoff voltage, setting 29). It won't b...

Hey coulomb, I work for a company in the field of Li-Ion battery technology. We have tons of Li-Ion-Batteries (NMC and NCA, so 3,7V per cell). we have VW E-Golf Batteries, VW Passat GTE, VW E-Up, BMW i3 and all other manufacturer batteries. A very typical batterie nominal voltage is 44,4V. Upper lim...
