Does anyone know the process to upgrade from 60A to 80A breaker in Cape Town? Is there an application process or can one just go ahead with it assuming incoming supply is compliant for 80A. Thanks.

Sounds like Christmas.... I've been looking at the US2000 B x 4 in a rack. How easy is would it be to hook these up to my current setup?

Thanks Chris , that would be fantastic and greatly appreciated. Are you happy with your Pylontech so far?

Hi Chris, Thanks for your valued input. My suspicions are probably confirmed then, i.e. the nightly mini-cycles and the Axpert charging bug has killed my batteries. Can anyone message me with a recommended installer in CT that understands Axperts and can upgrade firmware and perhaps assist with general maintenance in future? Any recommendations for battery replacement? Thanks again Chris.

BTW - attached is the label from one of my inverters.

Hi All, Newbie so go slowly please . System Specs: 12 x 260 watt ReneSola panels 2 x 5 KVa Axpert (RCT) Inverters in parallel 8 x Trojan T105 lead acid batteries No BMV installed System is 3.5 years old (other than checking the batteries this is the first time I'm having to try and learn quickly to solve my issues) Recently batteries started fizzing and bubbling away producing excessive heat and also leaking electrolyte. I reduced charging voltage and switched to Solar only as charging source to try and preserve the batteries while I attempted to work out what went wrong. My original installer has gone AWOL and no longer in business. Have had the batteries tested by another local installer and they confirm the batteries are done for. Original settings when batteries started their nonsense: Program Setting 00 ESC 01 SbU 02 20A 03 APL 04 SdS 05 FLd 06 Enabled 07 Enabled 09 50Hz 11 10A 12 48V 13 54V 16 Snu 18 Off 19 Stay at latest screen 20 Lon 22 AOF 23 byE 25 FdS 26 58.4V 27 54.0V 28 PAL 29 42.0V 30 OnE 31 SbE My questions: Is 3.5 years a reasonable life for lead acids? What is a recommended replacement as a storage solution? Lithium (Pylontech or similar)? Super Caps? Or Should I be getting a second opinion on the current batteries? Recommended Cape Town installer who understands the Axpert setup and can do the correct firmware upgrade? (Welcome to message me directly if it may be considered advertising). How do I determine the current firmware version? Been following the discussion regarding CoCT registration and am getting very discouraged regarding Axperts and Grid-tied Hybrid not being able to comply with the regulations – where to with this one? Original electrician did provide a CoC. Thanks for the great forum. Have already learnt a heap from following a few discussions.
