Technical FAQs 4

How long do Inverter Batteries last?

Battery backup duration varies based on battery capacity, load, and battery health. A typical 150Ah tubular inverter battery running a moderate load of lights and fans can last between 4 to 6 hours. Heavy appliances or higher load will reduce this time.

What is the charge and discharge limit of my inverter?

Please refer to the manual for the charge and discharge limit of your inverter. When selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current.

How do I set the charge/discharge current for the batteries?

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.

What is the maximum charge/discharge of a battery?

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.
