How to calculate DC to AC conversion?
The AC power is calculated by multiplying the DC input power by the inverter's efficiency. Then, the AC current is the AC power divided by the AC output voltage (for single-phase systems).
What is inverter efficiency?
Inverter efficiency is the ratio of output AC power to input DC power. Most modern solar inverters have an efficiency between 94% and 98%.
How much AC power do I get from 1000W DC?
If your inverter is 95% efficient, 1000W of DC power will yield 950W of AC power. The remaining 50W is lost as heat.
