Posted December 30, 20213 yr Trying to help a neighbor An installer from Pretoria, no need to mention names yet, he is not been very helpful, installed the following for my neighbor. 1 X 5.5 KW/h 51 V Hubble AM 2 battery 9 X 400 W solar panels. 1 X 5 KVA SFP 5000 ES Growatt inverter. He did not connect the BMS and the system is presently running without BMS. I'm a bit concerned that he is not damaging the battery. What should the settings be for the following parameters: This are the parameters settings on the growatt. 5-- Battery type 11-- Max Charging current 12 ---Setting voltage point back to utility source 13 ---Setting voltage point back to battery mode 19 ---Bulk charging voltage 20 ---Floating charging voltage 21 ---Low DC cut-off voltage will these settings as per manual be safe ?
