Mark Bryant

thanks so much Coulomb - it seems to have settled down now and resolved this issue itself.

Hi All, My name is Mark Bryant - I have recently registered to the forum. I have also recently installed two seperate Axpert 5kva inverter systems, one at home that has utility power and one at a camp where the is no utility power. The home system consists of Axpert (Mecer SOL-I-AX-5M) Inverter, 2 PylonTech US2000, and 6 325W panels (2 banks of 3). This system is running perfectly, with the inverter battery setting as per some of the forum thread suggestions I read. Yesterday I plumbed in the off grid camp setup that consists of Axpert (Mecer SOL-I-AX-5M) Inverter, 1 PylonTech US2000, and 12 325W panels (4 banks of 3). The reason for the extra panels is so that I can run a water pump and fridges during the day. When I connected yesterday the system fired up perfectly (see pic below and zoom into screen display) but after a while, without any warning signals I lots the output from the inverter to the load. I did get the HS/H5 indicator so from a prior thread I searched on this forum believe I must change programe 28 to 'SIG', but would this impact the load output. Is there anything else I can check? The setting on the offgrid system are as follows: 1 SOL, 2 20A, 3 APL, 4 SdS, 5 USE, 6 LtE, 7 ttE, 9 50Hz, 11 20A, 12 51v, 13 53v (not in SBU mode so 12 and 13 not relevant but is SOL the correct mode?), 16 OSO, 18 aON, 19 ESP, 20 LON, 22 AON, 23 byd, 25 FEN, 26 53.3v, 27 53v, 28 - not sure but will make sure SIG, 29 47.5v, 31 SbE If 31 was Sbd does it imply that the solar charges the batteries as first priority to max of "2" and supplies nothing to the load? Possibly I changed this in error. As I am new this is a bit of a roundabout of questions and my terminology might not always be correct but thanks in advance for everyone's help and input. Also the off grid installation is remote so any suggestions would be immensely helpful as I am out of comms when there. Kind regards Mark
