Solar Charging Box

A complete solar charging solution built into a single fiberglass battery box. The monocrystalline panel is mounted directly to the box, so there is no separate panel to mount or wire, and a solar charge regulator is already built in and ready to go. Just set the box in place, connect to your battery, and start charging.

Choose Your Variants at Checkout: Select the panel output and system voltage that fit your battery bank.

Panel Output: 20W, 28W, or 36W (box size scales with panel output)

All-In-One Panel and Battery Box Design

Rather than mounting a panel separately, this box builds the solar panel directly onto the battery box itself. There is no bracket to position, no mounting arm to run, and no extra wiring between panel and box. The battery sits protected inside while the panel charges it from above, all in one self-contained unit.

Three Panel Sizes to Match Your Battery Bank

Select the panel output at checkout that best fits your charging needs. Box size scales up with panel output to accommodate the larger panel footprint:

20 Watt: housed in a 16 inch by 14 inch by 8 inch fiberglass box, suited to smaller battery banks and lighter charging demand.

28 Watt: housed in an 18 inch by 16 inch by 8 inch fiberglass box, delivering extra charging capacity for larger setups.

36 Watt: housed in a 23 inch by 15 inch by 9 inch fiberglass box, the largest in the lineup, built for maximum charging capacity and demanding battery banks.

12V or 24V System Compatibility

Select the system voltage at checkout that matches your battery bank. A solar charge regulator wired for your selection is built into the box, so there is nothing separate to buy or install:

12V System: built-in 12V-5A solar charge regulator for standard 12V battery banks.

24V System: built-in 24V-5A solar charge regulator for 24V battery banks.

A user-friendly green LED shows at a glance that the regulator is actively working.

Durable Fiberglass Construction

Every size in the lineup is built from rugged fiberglass that stands up to sun, salt, and rain without cracking, corroding, or fading. This makes it a natural fit for boat lifts, docks, and other exposed marine and outdoor settings where a standard plastic box would not last.

Premium Monocrystalline Panel Technology

Every panel built onto the box features monocrystalline single-crystal silicon cells, the superior solar technology for efficiency and low-light performance. It is sealed with low-iron tempered glass and framed in anodized aluminum alloy, so it holds up to years of sun and weather right alongside the fiberglass box beneath it.

⚠ Important: The built-in solar charge regulator is wired for the system voltage you select and cannot be changed after purchase. Confirm your battery bank is 12V or 24V before ordering.
