- Ships from Las Vegas. In stock now. Free local pickup.
Why this battery
Built for the places most 48V batteries can't go. Many 280Ah wall batteries are indoor-only, which means finding room in a utility closet or paying extra for an enclosure. The GSL 14.34kWh is IP65 rated and bolts to the floor on its own stand, so it suits garages, barns, carports and sheltered exterior walls.
More of the battery you can actually use. GSL rates each module for 95% depth of discharge, so 13.6kWh of its 14.34kWh is usable. It is rated for 8,500+ cycles at that depth and backed by a 15-year warranty.
Start with one, grow to sixteen. Add modules as your loads grow, up to 16 in parallel for 229kWh. That covers a cabin, a whole house or a farm shop.
Inverter compatibility
This battery talks to your inverter over CAN or RS485, so the inverter reads state of charge and sets charging limits itself. If your inverter isn't listed, send us the model and we'll confirm before you order.

Frequently asked questions
Will it work with my inverter?
It works with all major 48V inverter brands, including Victron, Sol-Ark, EG4, Growatt, Schneider and Deye, with closed-loop communication. If yours isn't listed, send us the model and we'll confirm before you order.
Can I install it outdoors?
Yes, in a sheltered spot. It is IP65 rated and bolts to the floor on its own stand. GSL asks for a dry, shaded location between 32°F and 113°F, with 12 in of space above and in front and 20 in at each side.
How much power can I actually use?
About 13.6kWh per module. GSL rates it for 95% depth of discharge, and the 8,500-cycle rating applies at that depth.
Can it charge in freezing weather?
No. This model has no built-in heater, so it won't charge when the cells are below 32°F. It can still discharge down to −4°F. In cold climates, install it in a garage or insulated space that stays above freezing.
Can I add more batteries later?
Yes, up to 16 in parallel. Match the new module's charge level to the existing ones before connecting, as the manual describes.
Does it qualify for the federal tax credit?
No, not for new installs. The 30% residential credit (25D) ended for systems installed after December 31, 2025. Some states and utilities still offer battery rebates, so check yours.
Will it pass inspection?
It carries UL1973, UL9540A and UL9540 listings. Local code rules vary, so share the documentation with your installer or permit office early.
How is it shipped?
By LTL freight from Las Vegas, with liftgate delivery available. Shipping is calculated at checkout, and free local pickup is available.

Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
