Super support. Delighted I found them. System battery was down for quite a while and no one would try to fix it as GivEnergy out of business. A few hours later and I’m up and running again. Brilliant service!!! Highly recommend them.
Particularly useful in helping to fix my GivEnergy All in One system with a disabling fault.
My old solax packed in and was replaced by solar tech support. I am impressed at the very short time scale, sorted in only 3 days. Some were quoting 2-3 weeks. The old unit and all the packing was taken away.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.
As a Givenergy customer I have been forced to get familiar with my system since it developed battery failure. I managed to find someone to repair the battery and managed to do the physical install and connection. I reached out to Ron at Solar Tech Support and with the help of whatsapp and many screenshots of the system, cloud and App Ron managed to get me through getting it all up and running. Big thanks to Ron.👏👏
An amazing experience and service from Ronald - totally 100% recommend. All remotely sorted with no need to wait around for someone to pop in and sort. I was a little nervous about doing this but was really easy and he talks you through the steps. Just such relief and we are back up and running again.
Pylontech problems land in one of two camps: the battery will not talk to the inverter, or one module in the stack has tripped and taken the whole bank down. The first camp is nearly always configuration. Wrong battery type selected on the inverter, the comms cable in the RS485 port when the inverter wants CAN, a baud rate mismatch, or two modules both set as master on the DIP switches.
Module faults on the US2000C, US3000C and US5000 announce themselves with an amber or red LED. Amber is a warning, usually cell imbalance or high temperature, and imbalance gets common once a module passes three or four years old. Red is a BMS protection trip, and because the BMS treats a stack as one system, a single tripped module can shut down the entire bank. Our US series fault guide covers LED interpretation and module isolation, and the pairing guide walks through every comms checkpoint.
Before you chase settings: Pylontech only pairs with open-protocol inverters like Solis, Sofar, Victron, Lux and SolaX. GivEnergy is a closed system and will not accept a Pylontech battery, whatever you configure. Fox ESS lists only its own high-voltage batteries for its hybrid inverters, so a Pylontech battery is not a supported pairing there and may affect the warranty: see our Fox ESS support hub and our guide to adding a battery. The remote diagnostic is free, so start there.
Each topic links through to an engineer-led step-by-step guide.
Your Pylontech battery won't communicate with the inverter. The inverter shows a BMS fault, the battery LEDs look normal, and nothing charges…
See Pylontech not talking to your inverterOne module in your Pylontech stack has an amber or red LED. The whole bank has shut down, or capacity has dropped.
