Hi All, I need some guidance here. I woke up today to a dead inverter (Synapse 3.0+) and 2 Pylontech UP2500 lithiums. I contacted the original installer but he is currently offline and will hopefully get back to me later. Is this the best approach to contact him as my first port of call. Are there service providers in the industry who one can call for support similar to how one would call in a plumber? My batteries charge off Eskom and this is the first time this has happened. I see that the main inverter switch was left on and that probably had my lights and tv running directly off the inverter and not through Eskom and probably why the battery died? I have now switched off the main inverter switch in the hope that the batteries will charge but I’m not hopeful. I have had these batteries for about 16 months now. Any ideas or advice will be highly appreciated. Thanks

Yes best to call your installer. You should not drain the batteries if you have utility power available as soon as your batteries go below a certain soc( setting) the inverter should trigger"back to utility" and charge your batteries. Not sure about your setup or how your loads are connected( essential only) and what your total load consumtion is through the inverter but you should never end up with a flat battery if you have utility available. Can you post the setting of the inverter and the soc of your Pylontech batteries.

Welcome to the forum as i see you are a new member. Tell us more about your setup. Do you have solar connected. Do you have remote monotoring on your system?

Thank you, yes I’m new. No I do not have solar, the inverter charges from Eskom. I do not think I have remote monitoring.

Where do I check the setting and the soc. Apologies but I know very little about the technology. I am hoping to learn more from trying to resolve my current issue. I cannot reach my installer, I have now emailed him and hopefully he responds. Thanks.
