Whole house battery backup is a home energy storage system capable of powering your entire property — not just a few critical circuits — during a grid outage or period of high electricity cost. Unlike small portable power stations designed for camping or single appliances, a whole house system stores enough energy to run your fridge, lighting, router, air conditioning, and other essential loads simultaneously.
The GBP-L series is designed specifically for this application. With capacities from 13.44kWh to 32kWh per unit and support for parallel expansion, it provides enough stored energy to keep a typical 3–4 bedroom home running through an overnight outage — without a generator, without noise, and without fuel.
Step 1 — Charge The battery charges from your solar panels during the day via a compatible hybrid inverter, or from the grid during off-peak low-tariff hours overnight. The built-in BMS manages charging automatically.
Step 2 — Store Energy is held in LiFePO4 cells rated for 5,000+ cycles at 80% DoD. The wheeled cabinet keeps the battery accessible and ventilated — natural air cooling keeps operating temperature stable without a noisy fan.
Step 3 — Deliver When the grid goes down or solar isn’t producing, your hybrid inverter draws from the GBP-L and delivers clean AC power to your home circuits. Switching happens in under 10ms — fast enough that most appliances don’t register an interruption.
Stop paying peak-hour rates Charge the battery overnight when electricity is cheap. Use stored power during expensive peak hours. Homeowners on time-of-use tariffs typically recover the cost of battery storage in 5–8 years — and save every year after.
Stay powered through any outage Grid failures don’t announce themselves. A whole house battery system switches automatically in under 10ms — your fridge stays cold, your security system stays armed, your family stays comfortable. No generator startup, no fuel, no noise.
Make your solar panels worth more Solar generates peak power midday. Most households use peak power in the evening. Without storage, surplus daytime generation goes back to the grid at a low feed-in rate. With the GBP-L, it stays in your home — powering your evening for free.
No installation compromise The GBP-L requires no wall fixings, no structural assessment, and no permanent installation. Roll it into your garage or utility room, connect to your inverter, and it’s operational. If you move, it moves with you.
| Home size | Daily consumption | Recommended model | Runtime (no solar) |
|---|---|---|---|
| Apartment / small home | 10–15 kWh | GBP48-280L (13.44kWh) | ~20–22 hours |
| 3–4 bedroom home | 15–25 kWh | GBP48-314L (16.1kWh) | ~15–20 hours |
| Large home / EV owner | 25–40 kWh | GBP48-560L (28.8kWh) | ~18–24 hours |
| High consumption / off-grid | 40kWh+ | GBP48-628L (32kWh) or parallel | Full day+ |
The cost of a whole house battery backup varies significantly based on energy capacity (kWh) and power output (W) requirements. Systems like the GSL series provide an integrated solution including a 3500W hybrid inverter and 5kWh of storage. For larger needs, the GBP-L series offers modules up to 628Ah (approx. 32kWh), which provides professional-grade autonomy for residential and small commercial use.
Building a reliable system is simplified with GSO’s “All-in-One” design philosophy.
Select the Core: Choose an integrated unit like the GSL stacked or wheeled machines that combine the inverter, BMS, and batteries.
Scalability: Connect multiple battery packs in parallel on demand to increase capacity.
Integration: Use standard communication interfaces (RS485/CAN) to link the battery to the house’s electrical distribution.
Yes. GSO units like the GSL48-3.5K support four charging modes, including Mains Charging and Mixed Charging. This allows the battery to charge from the grid during off-peak hours (valley filling) and provide power during peak times or outages.
Maintenance & Noise: Batteries like the GBP-L series are silent (<60dB) and require no fuel or engine maintenance.
Response Time: Integrated systems like the GSL series feature a 10ms typical switching time, acting as a high-speed UPS to prevent electronics from rebooting.
Environmental Impact: Generators emit CO2 and noise; LiFePO4 batteries are “green” and environmentally friendly with no heavy metals.
Absolutely. GSO’s industrial and commercial systems, such as the BOC series or GBP-H2 series, are designed for diverse power sectors and can communicate with mainstream equipment. The battery can act as the primary buffer, only triggering the generator when the battery state of charge (SOC) reaches a specific low threshold.
The best backup utilizes LiFePO4 cells for safety and longevity. The GSL series is ideal because its pure sine wave output ensures that sensitive appliances like refrigerators, medical devices, and computers run without interference.
For home storage, yes.
Cycle ife: LiFePO4 offers 5,000 to over 25,000 cycles, compared to ~500-1,000 for standard lithium-ion.
Safety: They use high-performance cathode materials with excellent consistency and high thermal stability.
