Technical FAQs 4

What is the maximum charge current a solar inverter can charge?

Maximum Solar Charge Current: This is the maximum current the inverter’s MPPT controller delivers to the battery. For example, a hybrid inverter may support an 80A charge current, charging a battery at up to 80A based on its voltage.

How do I determine the maximum inverter power a car battery can support?

To determine the maximum inverter power that your vehicle's battery can support, you need to know the battery's rated voltage (12V for most automotive batteries) and the number of ampere-hours (Ah).

How much inverter power can a car battery support?

There is a theoretical limit to the amount of inverter power that can be supported by an automotive battery. Theoretically, the maximum supported inverter power can be calculated by multiplying the battery capacity (Ah) by the battery voltage (V) multiplied by the discharge multiplier (C-rate).

What wattage Inverter should I use?

Match the inverter’s continuous wattage rating to the battery’s discharge capacity. For a 12V 200Ah battery (2.4kWh), a 2000W inverter is ideal. Formula: Inverter Wattage ≤ (Battery Voltage × Ah Rating × 0.8). Factor in surge power needs but prioritize sustained loads.
