Better price, better materials. Let's assemble a home solar battery together.

What are the advantages of our DIY battery kit compared to pre-installed batteries?

1. Better Price.

Pre-installed solar cells usually come with many additional costs, undoubtedly increasing the consumer's purchase price. Our DIY kits, on the other hand, have a transparent price, including only the cost of all accessories.

2. More Robust Components, Giving You Peace of Mind.

Our battery box uses a 250A T-class fuse and a 250A heavy-duty DC circuit breaker, which are not found in similar products, providing excellent dual overcurrent protection. It also features 400A large conductive terminals and pure copper flexible busbars—all crucial conductive components for a battery, rarely seen in most pre-installed batteries.

3. Detachable Design, Easy Maintenance.

Compared to pre-installed batteries, our battery kit can still be safely disassembled after assembly. This facilitates later maintenance, management, and upgrades.

Pre-installed batteries, being completely soldered together, make individual repairs almost impossible, increasing maintenance costs.

EEL 48V 17KWH JK V3 vertical battery application
The EEL 48V JK V3 vertical battery box, equipped with a JK V19 BMS, features dual protection with a 250A DC circuit breaker and a 250A T-class fuse. It also includes a fire extinguishing device and comes with all necessary accessories, making it ideal for users who want to assemble their own home energy storage batteries.

Battery Handling Guidelines

1. Pre-Use PreparationRead the user manual carefully before operation and observe all labels and warnings on the battery surface.

2. Operational SafetyKeep the battery away from heat sources or open flames during use.

Avoid striking, dropping, or subjecting the battery to physical impact.

3. Prohibited ActionsDo not solder directly to the battery or puncture it with nails or sharp objects.

Never invert the battery. Avoid crushing, throwing, stepping on, or bending it.

4. Short-Circuit PreventionPrevent short-circuiting the terminals to avoid potential hazards or damage.

5. DisposalDispose of depleted batteries in accordance with local regulations. Never expose them to fire or water.

Safety first — Always wear appropriate protective gear and follow the manufacturer’s guidelines during handling.
