2-string, 500V DC Photovoltaic Protection Box, Pre-wired
The HA8 photovoltaic protection box provides complete electrical safety for solar installations with two strings, operating at voltages up to 500V DC. Factory-equipped with DC fuses, a main circuit breaker, and surge protection, it is a compact solution for residential and small commercial installations. The IP65 enclosure protects it against dust and water, making it suitable for both indoor and outdoor mounting.
What you get with this product
- Complete protection for solar panels against short circuits and overvoltages — 1000V DC fuses and LD-40 surge arresters included in the box
- Quick and safe disconnection of the entire photovoltaic system with a single DC C32 main circuit breaker, without additional tools
- Fast connection via pre-installed MC4 connectors — panel strings connect directly, without additional adapters or accessories
- Guaranteed weather resistance thanks to the IP65-rated ABS plastic enclosure, with no risk of infiltration or corrosion
- Compatible with standard inverters — the 32A DC output integrates directly into the equipment chain of any residential or small commercial photovoltaic system
- Verifiable CE and IEC conformity — internal DALBI components are labeled and certifiable, without compromising safety
How it works and how to install it
The HA8 photovoltaic protection box receives DC current from two strings of solar panels via the MC4 connectors on the bottom, protects each string individually with individual DC fuses (DALBI LQPV-32, 1000V, 10x38), and the combined current passes through the C32 main circuit breaker before exiting to the inverter. The LD-40 surge arresters (500V DC, Imax 40kA) protect downstream equipment in case of lightning or voltage spikes. Installation is done on a wall or on the panel structure, using the four mounting points of the enclosure; cables from the panels and to the inverter are inserted through the sealed cable glands on the bottom cover.
Frequently Asked Questions
Can I use this box with panels that generate more than 500V per string?
No. The maximum allowed input voltage is 500V DC; for systems with higher voltage, a box variant with a 1000V DC rating is required.
Are the MC4 connectors included or do I need to buy them separately?
The MC4 connectors are pre-installed on the box, on both DC+ inputs and DC- outputs, so that the cables from the panels connect directly.
Is it suitable for outdoor mounting, on the roof or on the facade of the house?
Yes, the IP65 enclosure protects it against rain and dust, being approved for outdoor installation.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The molded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
