21DEC2024: Overloading on full battery charge Issue below fixed for 12000XP with firmware 0405 for individual and paralleled systems. @ScrotpusGobbleBottom however reports this same issue on 6000XP for a DIY battery setup.
7DEC 2024: Long time lurker, first time poster. Engineer...Off-grid setup (no grid input or connection, though I can and do plan to hook up later).
Just had a 1x 6000XP running in this same setup without issue and am upgrading, or trying to...Got 2x 12000XPs to parallel with 4x EG4 wallmount batteries to share. Currently only hooked up 1x 12000XP to 4x batteries just like 6000XP just was and worked flawlessly. When batteries are fully charged or limiting charge, the unit will overload on the slightest load addition (normal is all of 500w). Letting the unit reset itself after overload goes right back into overload. If I turn OFF/disconnect PV, unit works fine from batteries. Plenty of sun out too...was charging batteries and loads with over 8k of PV before first overload and now that batteries are charged more (since it did when in overload), this is the pattern.
Did talk with Signature Solar tech support (bought system from another company though) and they thought it was a battery comms issue, and swapped battery type to 1. HinaESS; there's no option for EG4 like the manual says...I'm very frustrated.
I saw mention of a potential firmware on the 12000XP needed in another post but no meat in the discussion.
