Thus, we can take up to 150% of the ac power rating from our ESS to size the PV array. The Enphase Encharge has an ac power rating of 1.28 kWac per unit. Multiplying by 1.5, we find that we will need no more than 1.92 kVA (ac) of PV per Encharge unit. Finally, we use our PV array ac rating to calculate the number of IQ inverters for the …
