Pre-Charge ?

[AHTrimble]

Do the MNPowerflo5 batteries have the ability to pre-charge an inverter to prevent a spike when turning on the battery?

[FNG]

Yes they do, it is basically automatic internally on the BMS

Just for clarification... with this ability, at initial start-up, I can just connect the batteries to the Rosie Mobile and turn everything on?  No need to connect with a resistor briefly like in this video?

In my experience I've been able to precharge my power bus with my sccs, which then powers up the Rosie, then I connect my batteries to the bus. No precharge process needed.

since the pf-5 has an on/off button....and precharge is built into the BMS... you *should* be able to:
- with all breakers OFF (inverter-battery and batteries, and inverter/loads),
- wire up all connections, nothing is on, so no sparks .
- turn all inverter-battery breaker on
- one by one, turn batter breakers "on", and
- press, and hold pf-5 power on button for 3 sec and release. The BMS will boot and has pre-charge built in
