Photovoltaic Protection Panel 2 String 1000V DC
The HA12 photovoltaic protection panel ensures complete electrical safety for solar installations with two strings, at a maximum voltage of 1000V DC. Designed for small residential and commercial installations, the equipment integrates overvoltage protection, automatic DC fuses, and a main switch, all within an IP65 waterproof enclosure. This component protects your investment in solar panels against overvoltages, short circuits, and abnormal operating conditions.
What you get with this product
- Complete protection for the photovoltaic installation — DALBI LQPV-32 surge arresters (1000V DC) prevent damage to the inverter and panels in case of lightning or voltage spikes
- Quick disconnection of the entire system — the 32A three-pole switch with a red lever allows for complete isolation of the installation for maintenance or emergency situations, without additional tools
- IP65 weather-resistant enclosure — the panel can be mounted outdoors, on a wall or support structure, without the risk of water or dust ingress
- Pre-installed MC4 connectors on inputs and output — connection to solar cables is direct, without adapters, reducing installation time and the risk of connection errors
- Two independent string inputs with individual fuses — each string benefits from separate protection, so a fault on one circuit does not affect the other
- Compatible with residential and small commercial systems — accepts up to 2 x 15A per input and 32A on output, suitable for installations with inverters, storage batteries, and monitoring
How it works and how to install it
The HA12 panel is mounted on a wall or the metal structure of the photovoltaic installation using the included mounting elements — the ABS enclosure with a transparent cover allows for visual inspection of component status without opening the panel. Cables from the two strings of panels connect via MC4 connectors marked IN 1 and IN 2 (DC+ and DC-), and the output to the inverter connects via the OUT connectors. All internal components are pre-configured and factory-wired, so installation is limited to connecting external cables and securing the enclosure — no additional internal assembly is required.
Frequently Asked Questions
Can this panel be mounted outdoors, directly exposed to rain?
Yes, the enclosure has an IP65 protection rating, meaning it is waterproof against water jets and dust, making it suitable for permanent outdoor mounting.
Is it compatible with any type of solar inverter?
The HA12 panel is a DC protection device, placed between the panels and the inverter, and is compatible with any inverter that accepts DC input up to 1000V and current up to 32A.
What happens if one of the strings has a fault — does the entire installation shut down?
No. Each string has its own fuse, so an isolated fault on one circuit is stopped independently, and the other string continues to operate normally.
