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 80% depth of discharge 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. The brands below are on GSL Energy's 48V compatibility list. If your inverter isn't listed (for example EG4 or Sol-Ark), send us the model and we'll confirm with GSL before you order.

Frequently asked questions
How long is the clearance price available?
Until December 31, 2026, or until the 7 modules in stock sell out.
Will it work with my inverter?
GSL Energy lists Growatt, Victron, Schneider, Deye, Sunsynk, Luxpower and other major 48V brands as compatible, with closed-loop communication. For EG4, Sol-Ark or any brand not listed, send us the model and we'll confirm with GSL 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. The 8,500-cycle rating is at 80% depth of discharge.
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.
