enwitec BATBREAKER BYD HVM, HVM+ and HVB Combiner Box, 10019871
The new DC protection solution for BYD HVM/HVM+/HVB battery towers
With the BATBREAKER, enwitec introduces an innovative, user-operable and all-pole protection solution specifically developed for BYD battery towers of the HVM PREMIUM series as well as the new HVM+ and HVB series. The box enables the safe parallel connection of up to three battery towers. The BAT BREAKER reliably protects cabling and batteries in stationary PV storage systems.
Which systems is the BAT BREAKER suitable for?
The BAT BREAKER BYD HVM/HVB is currently the only ready-to-install solution on the market with all-pole DC circuit breaker protection for BYD HVM, HVM+ and HVB batteries. Unlike the BYD Combiner Box Plus, which relies on simple DC fuses, the BATBREAKER uses user-serviceable circuit breakers with thermal and magnetic tripping – a clear advantage when it comes to maintenance and servicing.
What makes the BAT BREAKER BYD HVM/HVM+/HVB special?
- With a rated current of 50 A, it is the ideal partner for high-performance inverters such as the Fronius VERTO PLUS
- All-pole protection instead of single-pole protection
- User-operable circuit breakers instead of hard-to-source fuses
- Specifically developed for HVM, HVM+ and HVB
- Robust control and switching technology
- Compact and installation-friendly design

Safety Instructions:
- Installation by qualified personnel: The installation of a PV storage system must only be carried out by qualified professionals.
- Ensure ventilation: Install the storage system in a well-ventilated area to ensure heat dissipation and prevent the risk of overheating.
- Observe fire safety regulations: Battery storage systems should be installed at a safe distance from flammable materials.
- Ensure accessibility: Install the storage system in an easily accessible location to allow for safe maintenance and emergency shutdown.
- Mechanical safety: Ensure that the battery storage system is securely fastened and protected against tipping.
- Danger from high voltages: Battery storage systems can generate dangerously high voltages. Avoid contact with exposed terminals or wires.
- Observe polarity: Ensure that the terminals are correctly polarized to avoid short circuits and damage.
- Suitable cables and fuses: Use only cables, connectors, and fuses recommended by the manufacturer.
- Grounding: Ensure that the battery and the entire PV system are properly grounded.
- Avoid short circuits: Keep tools, wires, or other conductive objects away from the battery terminals.
- Proper use: Use the battery only for its intended purpose and under the specified conditions.
- Proper disposal: Batteries contain environmentally hazardous substances and must be recycled or disposed of in accordance with applicable regulations for electronic waste.
- Danger from residual charge: Be aware that batteries can retain dangerous residual charges even after being switched off.
- No modifications: Unauthorized alterations, modifications, repairs, and opening of the product are prohibited.
