Product description
2 String 600V AC+DC Solar Combiner Box IP65 with Surge Protection & Breakers
Overview
This AC+DC Solar Combiner Box is a fully integrated protection solution for photovoltaic systems that require both DC string aggregation and AC grid interconnection. It combines 2 DC inputs (600V) and 1 AC output (400V) in a single IP65‑rated outdoor enclosure, significantly reducing installation space and complexity.
The DC side is equipped with a 2P 600V surge protection device (SPD), a 2P 600V/63A DC circuit breaker, and two DC fuses (one per input). The AC side includes a 2P 385V AC SPD and a 2P 400V/63A AC circuit breaker. All components are CE certified, ensuring compliance with European safety standards.

Frequently Asked Questions
Q： Can this combiner box be used for both the DC side from panels and the AC side from the inverter to the grid？
A： Yes. It is designed to accept 2 DC strings from the PV array and provide AC output protection after the inverter.
Q： Is the enclosure suitable for outdoor use？
A： Absolutely. The IP65 rating ensures it is dust‑tight and protected against low‑pressure water jets.
Q： Do you offer models with more DC strings or different AC voltages？
A： Yes, we can customize the number of DC inputs and AC voltage ratings. Please contact us with your requirements.
Q： What is the advantage of a combined AC+DC combiner box？
A： It simplifies the balance of system components, reduces the number of separate boxes, and centralizes protection, making maintenance easier and saving wall or pole space.
