Battery settings: Sunsynk 10kWh batteries
Hi all
I have a Sunsynk 12kW 3-phase inverter with two Sunsynk 10kWh batteries (SUN-BATT-10.24) and six Canadian Solar panels.
Recently, the inverter stopped communicating with the batteries (via CAN) and our installer has suggested that I switch the battery type from Lithium to AGM V for the time being to allow us to continue using the battery power. This seems to work as an interim solution, but I wanted to make sure that the Batt charge settings are correctly configured on the inverter.
The battery manual specifies the following:
* Nominal voltage: 51.2 Vdc
* Nominal capacity: 200Ah
* Charge voltage: 55.68 - 56.16 Vdc
* Discharge voltage: 45.6 - 56.16 Vdc
* Nominal charge/discharge current: 100A
* Max charge/discharge current: 200A
Currently, the following is configured on the Batt Charge screen of the inverter:
* Float V: 55.2 V
* Absorption V: 57.6 V
* Equilization V: 57.6V
Would someone with more experience please advise if these settings look correct or if I should configure different settings for the Float V, Absorption V and Equilization V given that the Batt Type is currently configured as AGM V and there is no BMS communication?
Many thanks
