Evening All I've searched long and hard and cant seem to get a definitive answer from the search bar. I'm hoping some of the more experienced users can shed some light. I've just installed a 3kw Must inverter + Must lithium battery combo including 2 x 420w panels. My previous setup was a 12v Mecer Axpert and based on similar settings everything seemed to run ok until today. Let me break it down 1st Question - During the day nobody is home and the load is very low. Solar charges up batteries and covers the load (+/- 150w) At night the load increases a bit but the battery manages to get through the whole night (Hits +/- 30% about the time solar starts to charge again in the morning) Issue comes in on the weekend or when someone is home. If we use battery to the set limit of 10% it switches over to grid and solar shows 0w, doesn't matter the time of day. Only when battery gets to 100% does it switch back to original settings. Should it not go straight back to solar provided there is enough to cover load and charge batteries? Settings below: 01 Output Priority - SBU 02 Voltage range - UPS 03 Voltage - 230v 05 Solar supply priority - LBU 10 - Charge source priority - CSO 11 - Max solar charge current - 100A 13 - Max utility charge current - 30A 14 - Batt type - Li 17 - Bulk charge - 29.2v 18 - Float - 27v 19 - Low DC Cut off - 22.8v 20 - Low DC warning and stop discharge - 23v ??? 21 - Low DC warning recover and battery stop charge -27v ??? 28 - Solar power balance - Sbd 37 - BMS control method - Vol 38 - SBU mode battery stop discharging - 20% 39 - SBU mode battery stop charging - 95% 2nd Question - I've connected the inverter and battery via CANBUS as per the manual and setup the Wifi on the inverter. On my app im seeing BMS data so im assuming the CAN communication is working (See below). Besides my app, is there an indication on the inverter itself that the CAN connection is successful? Note - the 'Li" logo on the screen is flashing. If any of this has been answered somewhere and I've missed it please point me in the right direction. Thanks in advance

Thanks @Douw Gerber These settings are definitely in line with the info I've been finding online. Previously I've used Synapse and Mecer with Hubble AM-4 but naturally they have the charge specifications on their site. The Hubble charge and float voltage is 1v more than the Oliter. I'm not sure if this is capacity related as Hubble is 110ah vs Oliter 100ah.

Good day All. Thanks for the amazing forum, I've been following for a few months. I've installed a few 48v back up systems which are all working great but I'm currently stuck on a 24v system. Can't seem to find charge settings anywhere online. Inverter is Synapes 3.0+ and battery is Oliter 24v 100ah Lithium (OTLVS25.6V). Any advice would be appreciated. Thanks Jp Johnson, CT
