GSL 10kWh Wall-Mounted Battery Reduces Energy Costs and Increases Self-Sufficiency

GSL ENERGY successfully installed a 10kWh wall-mounted LiFePO4 battery system (Model: GSL-0512200A-B-GBP2) for a residential home in Yemen, helping the homeowner combat frequent grid outages and reduce reliance on costly diesel generators.

In Yemen, where grid power is often unreliable and fuel prices continue to rise, energy independence is no longer a luxury — it’s a necessity.  With abundant sunlight during the day, the customer integrated their existing PV solar array with GSL’s storage system to shift energy usage into the evening hours.

System Capacity Impact:

A 10kWh battery enables the household to run:

Essential lighting and appliances for 8–10 hours at night

Air conditioning, TV, internet, and refrigeration during outages

Daily self-consumption of solar energy instead of using grid or generator power

Estimated Savings & ROI (based on local conditions):

Daily diesel generator reduction: ~4–5 liters/day

Monthly fuel savings: ≈ $150–$180 USD

Payback period: ~3.5–4.5 years depending on solar generation

CO₂ reduction: Over 2,000 kg/year of emissions avoided

Combined with WIFI monitoring, IP65 weather protection, and 6,500+ cycle lifespan, this system delivers both peace of mind and a strong financial return.

By leveraging solar power during the day and storing it with GSL ENERGY’s high-performance battery, the homeowner now enjoys:
Lower electricity costs
Full nighttime power coverage
Resilience during blackouts

This installation showcases how modern energy storage is transforming homes in off-grid and semi-grid regions — one rooftop at a time.
