Hello.
I have 2 LiFePO4 12,8 V / 200 Ah Smart (series cabling) on Multiplus (via BMS and Ac detector).
When in the evening, I launch a dishwasher, suddenly the voltage which is arround 25,0 or 26,0 V, drop to 18,7V (2,33 per cells) and immediatly go up to 20,0 V, 21,0V... to reach 25,0 V again.
On multi-plus we can read : CA Input (2600W), CA Output (2600W), and state : "Main power assistance" or "Direct Capacity".
I just want to know if it's normal in this case (relay ot the battery, by the main current), and without consequences for the battery lifetime, or if we have to change parameters, knowing that multi-plus parameters and mppt parameters are fixed with the template for LiFePO4, proposed by the software interface.
Best Regards.
