How to Size an Enphase Encharge Energy Storage System

As we mentioned all the way back in step zero, the ratio of PV ac power to battery ac power must not exceed 150%. 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
