TYPLE Battery Protection Boxes For BESS
Battery protection box is an IP-rated enclosure that provides DC-side distribution and protection for a battery energy storage system, housing a busbar together with DC circuit breakers (DC MCB and DC MCCB) on the link between the battery bank and the inverter or power conversion system (PCS). TYPLE battery protection boxes cover DC 250–1500 V and 1–800 A, in configurations from 1 to 32 inputs and 1 to 32 outputs, so one platform scales from residential storage to large commercial systems. They are engineered to align with IEC 61439, with DC circuit breakers designed to IEC 60947-2; component-level certificates are available through TYPLE’s qualified supply-chain partners.

Applications of Battery Protection Boxes
Residential storage: protected DC link between a home battery and hybrid inverter. C&I storage: disconnection and fault protection for commercial BESS. Off-grid & harsh-site: IP68 TPNBAT sealing for flood-prone, coastal, or high-humidity installations; metal-enclosure TPBAT for low-temperature sites down to −35 °C.
Advantages of TYPLE BESS Battery Protection Boxes
Integrated DC circuit breakers help protect against overloads and short circuits, reducing the risk of damage to connected equipment.
Busbars and protection components share one enclosure, keeping connections organized and simplifying installation between battery banks and inverters or PCS.
Centralized circuit breakers provide convenient points for disconnecting battery circuits during inspections and servicing.
TYPLE customizes voltage and current ratings, circuit arrangements, and enclosure options to match your battery storage system and installation requirements.
Types of TYPLE Battery Protection Boxes
TYPLE offers two battery protection box series — TPBAT (IP65, metal) and TPNBAT (IP68, PC+ABS) — covering DC 250–1500
V and 1–800 A in 1–32 input / 1–32 output configurations. The table below compares them at a glance.

Battery Protection Box Internal Configuration
A TYPLE battery protection box integrates:
- Busbar — main DC current distribution within the enclosure
- DC MCB — miniature DC circuit breaker for branch overcurrent protection (IEC 60947-2)
- DC MCCB — molded case DC circuit breaker for main disconnection and higher-current protection (IEC 60947-2)
Breaker ratings and box size are configured to your storage single-line diagram.
OEM & Customization
TYPLE offers OEM and ODM battery protection boxes, configuring the busbar, DC MCB / MCCB ratings, string count, and IP class (IP65 / IP68) to your storage single-line diagram, with short lead times from the Liushi low-voltage supply hub. Send your battery bank voltage, current, and string layout and we build to spec.
Frequently Asked Questions
It provides DC-side distribution and protection between the battery bank and the inverter/PCS, combining a busbar with DC circuit breakers (MCB / MCCB) in one enclosure.
Both cover DC 250–1500 V and 1–800 A. The TPBAT series uses a metal enclosure rated IP65 and operates from −35 °C to +70 °C, suited to low-temperature sites; the TPNBAT series uses a PC+ABS enclosure rated IP68 (submersion-grade) and operates from −25 °C to +60 °C, suited to flood-prone or coastal sites.
They cover DC 250–1500 V (low voltage under IEC) and 1–800 A, in 1–32 input / 1–32 output configurations, scaling from residential to large commercial storage.
