How to convert DC to AC - the inverter The inverter is the electronic device that converts DC to AC in a two steps process: First of all, it turns DC into AC, then it increases the input voltage (12V, 24V) to reach an output of 230V usable by all appliances. This means it stores less and less power the more you use it. 3. Calculate the phase current I in amps (A) by dividing the power P in watts (W) by the square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V): (The power factor is the ratio of the real power flowing to the load to the apparent power in the circuit. Let's calculate what then the maximum allowable. Since there was a lot of them, it required around 9 Amps of current to lighten up at full brightness. in a single pass. Now you know everything you need to know to do the calculation, and what other factors you might need to take into account if there is any variation in your solar power system.
