    Hi all, been a minute since I was last here. Has anyone had issues with their Solis Hybrid not charging/discharging at the full rate like it used to?

    I'm not sure exactly when this happened but the max I see discharge is around 3.5kw and max charge is around 3.8kw. This is right at the beginning and throughout a charge/discharge so it's not like it starts high and then throttles. I did note while looking at the screen that the charge/discharge rate did flick between 2.5-3.5k even though the load was consistent. It never did this so something clearly wrong somewhere. I have power cycled everything including the BMS.

    It's hooked up to a couple of packs of 16s EVE with Seplos BMS. Controlled and monitored by HA.

    I'm thinking it might be a faulty inverter (or BMS?) but wanted to run it by you first.

    My own system is newly setup Solis 5kW with Seplos battery and I have observed it charging and discharging at 5kW as recently as 2 days ago. I have the V3 BMS. I suppose to rule out a faulty BMS, you could connect 1 battery at a time and see if that improves your chg/dischg rates.

    I do have an inverter issue where the datalogger is not communicating with the inverter. It's only in since March. 2 dataloggers have been tried. I'm told I need a new inverter (warranty covered). Disconnecting it from the grid in settings accidentally and then reconnecting seems to have caused the issue, but there's no explanation as to why. Mad stuff.
