I am seeking some advice regarding my battery upgrade. I am planning to add a 5.32kW battery to my existing 5kW inverter, but I have been informed that Sunsynk has discontinued its batteries. As a result, I would need to purchase a 5.32kW Eenovance battery, which was originally the manufacturer behind Sunsynk batteries.

I understand that the Eenovance battery must be set as the master, while the existing Sunsynk (Sun-Batt) battery would function as the slave (see attached document). Additionally, firmware updates for the Eenovance battery would be managed via Wi-Fi, whereas the Sunsynk battery would require a manual PC connection for updates.

There are still some Sunsynk batteries available, but here’s the issue: they are approximately R8,000 more expensive than Eenovance batteries, plus an additional R3,600 installation fee. Given that Eenovance originally manufactured Sunsynk, is it really worth spending the extra R8,000 for a Sunsynk battery even though there might be a firmware update issue?

I was quoted the fee for installing an additional battery by the original installer and supplier, but on another forum, I was advised that the cost is too high. What would be a reasonable price?

I would greatly appreciate your opinion on whether Sunsynk or Eenovance would be the better long-term investment and an acceptable instalation fee for 1 battery.
Thank you.
