Could someone please advise if this adapter will work to connect to the python? http://www.haitronic.cn/index.php?route=product/product&product_id=647

I have now also upgraded the firmware. The inverter console say my version is now LF1.73.00E. Is that correct?

My Float is also set at 51.8

Thanks for the suggestion Coulomb! I have changed setting 26 to 52.4 (it was on 52.5), I will monitor and see if it helps.

My system ran fine for the last two weeks since I installed the new battery, but the last two days the inverter stopped with an error 52 (bus voltage too low). It works fine again after I restart it. Both days it happened around 12 o'clock during the day, once the battery is almost fully charged. I never had this issue on my old batteries. I didn't upgrade the Axpert's firmware. Any advice would be appreciated.

Thanks wolffandy, I will make the changes.

I have set the bulk charging voltage at 53.2 and Float at 52.2 Is that fine?

Thanks for the reply Coulomb, I appreciate it!

I'm about to upgrade my old batteries to a PylonTech US3000C. I have a RCT-Axpert 5K inverter(I have attached the label for the inverter). Would appreciate if someone could help with the following: I assume I must upgrade the firmware, is the dsp_LF1_74.40e pf1 the correct one? Do I have to install the communication cable between the battery and inverter. Other than for monitoring, do I need the icc software? Which Amp dc fuse is recommended between the battery and inverter?

That is also how I understand it, my manual say you must preferably use the 20 hour capacity rating.

This is a good idea.

Thanks everyone for the help, I think my system is now protected. I'm just not sure about lighting protection. I live on the Highveld and we can get severe thunderstorms. I have grounded my panels and inverter but I see some people also ground their batteries, is it really needed?

Thanks Chris and Don, I think I got it now.

Bought the Mersen fused battery disconnect with 2 160A fuses, will install tomorrow then I'm sorted on the battery side. ACDC quoted me R 3 150 for a DC disconnect which is a bit steep. I'm considering a DC breaker between the panels and the inverter but I have no idea which size to get.

Thanks for the help Chris, I really appreciate it! The easiest for me will be to add an inline fuse holder for each string. Will 20A fuse for each be okay? Would a disconnect like this one work: https://new.acdc.co.za/pages/product-individual?GW96186
