Got Questions?

Quality lithium-ion battery systems last 10-15+ years with minimal maintenance. LFP batteries can achieve 3,000-6,000+ cycles while NMC batteries typically deliver 800-2,000 cycles. The SolarEdge Home Battery offers unlimited cycles for 10 years.

Yes! Most battery systems are compatible with existing solar installations. AC-coupled batteries like Tesla Powerwall and Enphase work with any solar system, while DC-coupled systems may require inverter upgrades.

Your battery system automatically detects the outage and switches to backup power within seconds, keeping your essential appliances running without interruption.

Minimal maintenance is required. Modern lithium-ion batteries need only basic monitoring through smartphone apps and occasional cleaning of vents. No regular servicing needed.

Installation is typically included in the system price. The physical installation takes 1-3 days, though permitting and utility approvals can take 2-5 months total.

This depends on your energy consumption and backup needs. Small homes (1-2 people) typically need 5-10 kWh, medium homes (3-4 people) need 10-15 kWh, and large homes (5+ people) often require 15-20+ kWh.
