Is battery storage worth it in Exeter under PG&E NEM 3.0?

Under PG&E NEM 3.0, battery storage is essential for Tulare County homeowners. High summer temperatures and AC loads make evening battery discharge highly valuable. In Exeter, summer electricity rates peak in the evening when solar production has stopped — battery storage lets you use your own solar power instead of buying from PG&E at peak rates.

What is the outage and PSPS risk in Exeter?

This area has elevated PSPS risk due to proximity to foothill transmission lines. Battery backup is strongly recommended, particularly for households with medical equipment, well pumps, or home offices. Moderate. Foothill location means higher PSPS risk.

What inverter do I need for EG4 batteries?

EG4 batteries work with most 48V hybrid inverters including Sol-Ark 15K, Growatt SPH, SRNE HF series, and others. Robbins Energy typically pairs EG4 with Sol-Ark for the most capable and well-supported combination. We handle inverter selection, battery sizing, and the full installation.

How does EG4 compare to Tesla Powerwall in price?

EG4 batteries typically offer more kWh of storage per dollar than Tesla Powerwall. The trade-off is that EG4 requires a separate hybrid inverter (like Sol-Ark), while Powerwall 3 includes its own inverter. For homeowners who need maximum storage capacity on a budget — particularly in foothill and rural areas — EG4 is often the better value. Robbins Energy can provide quotes for both options.
