Free QuoteUse our battery charge and discharge rate calculator to find the battery charge and discharge rate in amps. Convert C-rating in amps. Note: Use our solar battery charge time calculator to find out the battery charge time using solar panels. If the C-rating is mentioned as C/n (any number), in this case, C = 1. (E.g, C/2 = 1/2 = 0.5C).
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.
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.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
One battery charging or discharging at 50A will discharge at 58.4V x 50A = 2.92kWh. The charge and discharge current in the inverter settings is the total charge and discharge current of all of the batteries connected so 2 batteries would be able to charge or discharge at 100A, 3 batteries at 150A, etc.…
A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
