Good day. I have an UP5000 battery and attempted to update the firmware. I got the firmware from a support person in South Africa who encourage me to do this. The Serial number is K20110C32260597. The battery does not switch on now. All LED’s are dead. If I attempt force upgrade, I get error as below. I suspect I was given incorrect firmware as there are different chipsets? The mentioned support person now does not come back to me. Can anyone tell me where to get the correct firmware or point me in any direction of someone that can assist me? Much appreciated.

Good day. I want to rebuild my entire solar system. I currently have one Growatt SPF5000 inverter and have obtained another one which I plan to connect in parallel. In addition, I have three Pylontech UP5000 batteries and have now purchased another three US3000C batteries because the UP5000 is no longer available. That is the easy part. My question concerns the solar panels. I currently have 12 panels as indicated on the attached document, all less than two years old. The JA and Hyundai panels are no longer available. I am considering buying another four Megatron 460W panels and connecting two strings of eight panels each to each inverter. Are there any suggestions on which combination I should use, and are there any major disadvantages to using the existing panels with such a combination? Thank you very much.

Thank you, did a quick search, it seems dodgy.

Good day. Does anyone have experience with Sun batteries? I’m considering buying two of them but am a bit reluctant since it is not in my knowledge a known brand. Price for the kw seems good? SUN 51.2V 280AH 14.34KWH A-GRADE LITHIUM BATTERY CNY51281RN - Cubed Solar

Thank you.

Good day The Shoto HP10-Box5 lithuim batteries are stackable (Floor standing) The bottom part where one stacks the batteries on - what is it called and can anybody tell me where I can purchase it? See attached pic. Much appreciated.

Good day. I currently have three Pylontech Batteries UP5000 running of a Growatt SPF5000ES Inverter. They are Two years, 1 year and six months old. I can get two secondhand Pylontech US2000 batteries at a very reasonable price. Would you recommend mixing them with my batteries and if so in which order shall I install them? I know one UP5000 has to be the master, but not sure about the rest. Much appreciated.
