Hi Guys Im busy doing a installation for a client we did the first part of the installation battery backup only. He had a old 40kva UPS system in the house with 35 Lead acid cells system could only handle a hour then it was kaput. He has a mayor issue on his bills with eskom aswell with the UPS on he pulled a extra 5amp per phase. Upon closer inspection there was a short on one of the batteries but none the less we installed the new system came out awesome. 5kva Kodak hybrid per phase each on a 5.12Kwh battery. We going back for the PV's soon.

Hi there need some information please So i have a client who added JA Solar 250W Panels yonks ago. He wants to now add a new set of strings to push more to the inverter but i cant find those 250W panels anymore. He has 3 strings at the top of 5 each making about 1.25kW x 3= 3.75kW He wants to install a 5kW inverter and remove the 3kW Now heres the question can i add another string of 5 x JA Solar 345W Panels to make up 1.72kW?

Hi Guys hope you well. I have done a few solar installs but i never did the physical setups of the system so thats a bi of a grey area. I installed a quottro, Venus GX, Smart meter and then 2 Hubble batteries. I have bothered the poor guy by hubble so much i thought ill try and research a bit before i bother him again cause his been such a great help so far. I firstly would like some help with the settings i think thats my number one priority i had a look on google and victron but it doesnt seem as if im getting the right info can someone maybe help me out there NR2 everything is running great but i cant seem to get the second battery going guy from hubble said theres a black cable but i think someone by the client misplaced it i cant find it. Can anyone give me the pin settings for the rj45 please i have tried a few already but i think they wrong so i would like a confirmation please. I tried one of the RS485-A setups from axpert but it doesnt seem to work. I also tried the RS485-A from pylontech and that also didnt seem to work. One thing im not sure of is the dipswitch settings on the battery. thx for any help in advance
