Home Battery backup

Enphase battery backup —
hurricane season protection

Solar + Enphase battery backup means your home keeps running through any outage. No generator, no gas, no noise — just quiet, automatic protection.

Solar-assisted

Indefinite

Your panels recharge the battery faster than you use it, assuming proper usage as instructed by May Electric Solar and normal weather conditions.

Estimate only, based on 5.5 peak sun hours for the Central Florida area and typical appliance draw. Central A/C is estimated at 800W per ton assuming 15 SEER or better, and the microwave and well pump by typical daily run time (about 15 minutes and 2 hours a day) rather than continuous use. Load shedding assumes Central A/C shuts off at 30% battery to reserve the remaining charge for critical loads. A water heater, when added, runs only on daytime solar surplus (battery 95%+), about 1.5 to 2 hours a day, so it does not reduce backup runtime. Load shedding and proper use of your battery system as we design it will help achieve these estimates or longer. We'll size your solar and battery system based on your home's usage.
