Hi All. I have an Axpert ( Mecer ) 5Kw inverter, connected to the ICC software, which is working very well. I have 9 x 360w Canadian solar panels. Panels are 3 in series, and then 3 banks. The total solar power is then 3240w. Question 1: ( P=I x V ). The ICC software has read solar loads of up to 3713w, but if you times the reading from ICC ( 121.10v x 65A = 7865w ) So why are the PV readings not correct, or am I missing some info here? See Pic's attached. Question 2: The inverter states that it can have a Max PV input of 4000w. Does that mean that I can add 3 more 360w panels taking my PV potential to 12 x 360w = 4320w, but the inverter will only max use 4kw ? Or will I actual blow it up ? Thanks for the help all.

Thanks for all the info PhilFM.

Hi All. I have an AXpert 5KW inverter also connected to utility power ( eskom ), with 9 x 360w Canadian solar panels and 4 x Probe 12TE220 ( http://www.probegroup.co.za/LinkClick.aspx?fileticket=gHjZzUNluW0%3d&portalid=0 ) batteries. With this I have the ICC software with the victron BVM700. This system is hosting a critical server room drawing +- 950w 24/7. System is setup in UPS mode. In general ( for now ) I would like to save the batteries as most as possible and have them charged at 100% ready for when there no utility power at night. I have some questions would would love some help on this: I've used the "Use time for control" from 0900-1600. System switches over from utility to Battery(solar) mode at 0900, but does not switch back to utility at 1600. It only switches back when the PV voltage reaches 0v. My guess is that this has something to do with the "charge source priority" and the "output source priority" which is currently set to "utility first" ? any help :-) Under the "Use time for control" I have 3 option, utility, SBU, SUB. What is the difference between SBU and SUB? how does this work? Under "inverter setting" currently battery type is set to flooded. I guess this is wrong? But what should the charging current, Back to grid voltage, Bulk charging voltage, and Float charging voltages be with these batteries I have: ( http://www.probegroup.co.za/LinkClick.aspx?fileticket=gHjZzUNluW0%3d&portalid=0 ) Some system screenshots below. Thanks for all the help in advance, and let me know if you have any questions. Thanks Regards
