Questions We Get a Lot
A whole-home backup system is sized and designed to power your essential circuits — and in many cases your entire home — during a grid outage, not just a single device or appliance. The key specs to look at are continuous output wattage, peak surge wattage, and total stored capacity measured in watt-hours. The higher those numbers, the more of your home you can run and for how long.
LFP stands for lithium iron phosphate, a battery chemistry known for its thermal stability, long cycle life, and safer discharge characteristics compared to older lithium-ion formulations. For home energy storage, that means a battery that holds up through years of regular charge and discharge cycles without significant capacity loss. It's one of the most important specs to look for when evaluating a system built for daily home use.
A useful starting point is to identify your critical loads — refrigerator, lights, medical devices, router, phone charging — and add up their wattage and estimated daily run time. Most households find that 3,000–6,000Wh covers essential needs for 12–24 hours, while larger or expandable systems can bridge multi-day outages. Checking the continuous output rating is equally important, since a system with high storage but low output may not start high-draw appliances like HVAC or well pumps.

About Our Whole Home Solar Battery Systems
Whole-home solar battery systems are purpose-built energy storage solutions designed to capture, store, and distribute electricity for residential use — whether you're connected to the grid, operating off-grid, or preparing for outages. At their core, these systems pair a high-capacity battery bank with an inverter that converts stored DC energy into the AC power your home already runs on. They're built for homeowners who want energy independence, utility bill relief, or a dependable backup layer when the grid goes down. When choosing a system, the most important factors are total storage capacity (measured in watt-hours), continuous and peak output (measured in watts), and battery chemistry — with lithium iron phosphate now widely regarded as the go-to choice for home applications due to its long cycle life and stable performance. Expandability matters too: some systems are designed to grow with your energy needs over time. Think carefully about your critical loads, how long you need to run them, and whether you want the system to integrate with existing or future solar panels. The right system is the one sized for your household's real demands.
