Pylontech Battery Problems

Featured Replies

Hi, I'm looking for some help with my solar and battery backup installation in Sandton (Johannesburg). I have a failure on the master battery (red light) and one other is not charging. Can anyone recommend a technical service support team/person/company to come to site and check if the problem is software/hardware/inverter and then recommend a solution. Thank you.

@Gavin Heron ,

It will be useful if you can supply a bit more info on your system, like Inverter & Battery, make and model, as well as how your system is configured, as it may help pinpointing a resource that has come across this scenario before.

Thanks @ Sidewinder. 4 x Pylontech batteries (2xUS3000C, 2xUS3000), 8kW Deye inverter (SUN-8K-SG01LP1-EU), 14 x 340W panels.

thanks for your reply Shockin. It didn't work. I took it to Segan Solar for repair and am expecting their finding today.

Hi there. Did you ever get feedback from Segen? They would have downloaded the logs and sent then to China analysis. There is a likely chance that they will reject your claim stating the batteries have been overcharged. "Common problem"

I got my battery back and fixed. Nothing was wrong with it. The voltage was low. They recharged it and it is working now. They sent it to the Durban branch for fixing

Hola, necesito ayuda con la instalación de mi sistema solar y de respaldo de baterías en Sandton (Johannesburgo). Tengo una falla en la batería principal (luz roja) y otra no carga. ¿Alguien podría recomendarme un equipo/persona/empresa de servicio técnico que venga a comprobar si el problema es de software/hardware/inversor y recomendar una solución? Gracias.
