  1. Hi Guys I have installed 2 x SPF 5000ES Growatt inverters (parallel) 5kWp solar array on each and 3 x Shoto 5.1kWh Life Po4 batteries. The battery BMS is not connected to the inverter I setup the battery setting (parameter #5 to US2 for Li Batteries without BMS connected. I also setup the inverter as SBU so I can maximise savings on my Utility Bill. however during the day the load is powered from the Sol as soon as the sun go down, the inverter does not switch over to battery it switches to Utility. I need the inverter setup to be Solar first then Battery and if batter voltage is down to 46V i need it to go on utility. If someone can please help.
