You set the charge/discharge current for the batteries on the inverter in the battery setup page of the settings menu. The Sunsynk 5.12/5.32kWh batteries have a capacity of about 100Ah and a 50A continuous charge/discharge current so you can set the capacity charge and discharge using these values.
Although the batteries have a continuous charge or discharge current limit the inverter will also have its own charge or discharge current limit. This will apply no matter how many batteries are installed. Please refer to the manual for the charge and discharge limit of your inverter.
For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current. Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge is limited to the 90A of the inverter. Other Current Limiting Factors Your current should also be suitable for the rated current of your battery cables.
This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer.
The maximum charge and discharge power is 3 kW 2 3 4. Since the capacity of the battery is 75 Ah 2, we need to find the C-rate. One way to do this is to divide the maximum charge or discharge power by the capacity and voltage. This means you should set the charging current and discharge amps to 1.29 amps for this battery.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
Recommended Charge & Discharge Settings for Sunsynk
If you stick to 100A from the inverter divided across two batteries, that''s spot-on with the manufacturer''s recommendation. The nominal charge/discharge current on each battery is 50A. One battery could take max 100A if you have to, but that might shorten its life.
