Battery storage
Solar Battery Storage in Costa Rica
Batteries store the sun you produce during the day so your home or business runs at night and through power outages. Soul Ra Solar designs and installs LiFePO4 battery systems for hybrid and off-grid properties.

What a solar battery does for you
Backup power
When the grid fails, the battery keeps selected circuits such as the fridge, lights, internet and pumps running automatically.
Nighttime electricity
Solar energy collected in the day is stored and used after sunset, reducing what you buy from the grid.
Power outages and rainy season
Storms and grid faults are common in rainy season. Storage keeps your property running when they hit.
Hybrid systems
A hybrid inverter blends solar, battery and grid so your existing electrical system keeps working as usual.
Off-grid systems
Where there is no utility connection, batteries are the heart of the system and are sized to carry you through cloudy days.
LiFePO4 batteries: capacity, lifespan and warranty
We use lithium iron phosphate (LiFePO4) batteries because they are safe, handle deep daily cycling and last many years. Capacity is measured in kilowatt-hours (kWh) and tells you how much energy you can store. Lifespan is rated in charge cycles and depends on depth of discharge, temperature and the quality of the system design. Warranty terms vary by manufacturer and model, so we share the exact terms for the batteries in your proposal.
How we size a battery
List your critical loads
Fridge, lights, Wi-Fi, pumps, air conditioning and anything else that must keep running.
Estimate hours of backup
How long you want to run those loads without the grid, overnight or for several hours of outage.
Match the inverter
The inverter must handle peak power, such as starting a pump or an air-conditioning unit.
Add room to grow
Modular batteries let you add capacity later as your needs change.
Solar plus battery ROI
A battery adds cost but also adds resilience, evening savings and independence from the grid. The payback depends on your electricity rates, your outage exposure and how you use power. We model your situation during a free consultation. See our solar panel cost guide for what drives the price of a complete system.
Frequently asked questions
LiFePO4 batteries are rated for thousands of charge cycles, which commonly translates to many years of daily use. Exact lifespan depends on the model, depth of discharge, temperature and system design.
It depends on which loads you want to back up and for how long. A home that only backs up lights, internet and a fridge needs much less than one that also runs air conditioning. We size it during a site visit.
A basic grid-tied system shuts down for safety. A hybrid system with a battery and the right inverter keeps supplying your selected circuits during an outage.
Often yes, depending on your current inverter. We can assess your system and recommend a retrofit or an upgrade.
