Thanks Chris should i and can I add more panels ? cheers george

Thanks Pilotfish That makes sense , I will try the settings and let you know how I go. Generator is 18KVA. Cheers George

Thanks Chris , batteries are 1288 ah @20c yes 56,5 v was the battery voltage whilst the generator was still running this am. almost immediately after turning generator off the voltage dropped to 50,1v each Axpert is linked to 3 Strings of 3 panels of 255 watts each so 45 panels in total Set to charge at 10 amps per axpert off generator what should I use as bulk and float voltage ? cheers george

Thank you all for the advice so far. I am moving forward , I have followed the setup as per video on the bmv702 as from paulF007, I have the pi working and the icc software running. But i do not think my batteries are charging up properly ? I measured them this morning with a hydrometer - picture attached. I ran on generator through last night and voltage was reading 56.5 as per viltron BMV702 pictures attached. 10 minutes off generator batteries reading 50,1 volt ? load was 1500 watts max. If i read the instructions that came with the rolls battery they suggest bulk charge at 60 v ? the axpert allows 58,4 v ? I have attached some pictures of settings and set up. Would be most grateful for any more suggestions ? cheers george

Hi I need some help setting up a BMV 702 , It will need to be a step by step guide for dummies? I have 5 x axpert 5kva inverters in parallel , 1 x string of 24 x 2 volt rolls lead acid batteries set up is off grid. I also have a raspberry pi that I'm trying to integrate? any settings / advice would be greatly appreciated. cheers george
