Irrisol

Hi All. I recently completed a 7,2kW Kodak installation, with a 5X Pylontech US3000C battery backup. Batteries are connected in parallel using Pylontech lead out cables, to a common busbar, and from there to the battery fuse and then inverter with a common cable. I am however having issues with the master battery, that keeps tripping on an over voltage protection fault( other batteries continue functioning normally). Have updated firmware to V1.9 on all batteries and yet problem persists. Sent battery back to supplier, they tested it and it according to them, is not faulty. System has been running without issue for 2 weeks without this battery. Were could a possible other fault be, as the supplier maintains battery is fine. Also tested amps under load, master battery was read about 8A whilst other batteries were balanced at about 13A, so that seems to me to be a battery fault, correct?

Hi all, Installed a solis 4g Grid tied system, and CT keeps giving Range error. Checked ratio and it is set correctly. Customer has a rural supply on prepaid, with the control panel of meter that plugs into wall outlet, and uses PLC (power line communication) to communicate with meter unit at eskom supply point. My question is, if I was to re-wire a plug, so that this meter could be plugged in between CT and Grid, would this resolve the issue. Also customers DB board is a mess of wires, could this create interference with the CT clamp. I have never had this issue and am stumped

Hi Coulomb, You've been a great help. Final question, besides the two files I downloaded, do I need any other software on my computer to do firmware upgrade?

so download and unzip these files onto a flash drive and update firmware as per instruction manual correct?

so basically download and unzip these two files onto a flash drive, and then do firmware upgrade as per installation manual correct?

stupid question sorry

where does one obtain this firm ware?

Hi everybody, I have a system which is about three months old, 2x Kodak king UPS inverters, with PV and a 20kWh Pylontech battery back up. System was working fine until friday past. Customers eskom has been down since Thursday, now the system keeps giving hassles. The master inverter shows battery full, whilst the slave keeps giving a battery low error. What must I look for regarding faults, batteries are all still balanced and fully operational, but system literally keeps switching its self on and off. Would an ICC(inverter control center) sort this issue, or is that, as far as I understand, simply for online monitoring? Thanks
