Inverter trip due to excess ripple voltage on battery terminals. System worked fine with Gel batteries but after replacing with 400ah Lithium problem started especially when batteries at 100% charge.

Multiplus tripping due to excess ripple voltage after replacing battery bank
Hi @Frans
What causes DC ripple, and what you can do about it, is explained really well in chapter 2.6 on page 12 of Wiring Unlimited.
Also important on new lithium batteries is to give the system time to balance properly. This is done by a long, slow, low continuous charging current up to the target charge voltage, and holding it there. The longer, and slower that this happens for initially, the better.
