ABB miniature circuit breaker designed for photovoltaic DC circuits up to 1200 V DC.
ABB's S800PV-S circuit breakers are designed for the DC side of photovoltaic systems up to 1200 V DC. They protect cables and equipment against overload and short circuit and allow safe isolation of PV strings and arrays.
According to ABB, rated currents up to 125 A are available. Breaking capacity depends on the specific variant, so the exact catalogue number should be selected for the application.

It depends on how much electricity you use, when you use it, and the space available. We review your electricity bills and loads during a site survey and size the system accordingly.
On-grid systems work with the utility supply and need no batteries. Off-grid systems run independently with batteries. Hybrid systems combine both, so they can keep essential loads running during power cuts. We recommend the right type after understanding your needs.
Yes. Panels still produce electricity on cloudy days, although output is lower than in full sunshine. Systems are sized with seasonal variation in mind.
Mainly regular cleaning of the panels to remove dust, and periodic inspection of connections, protection devices, inverters and batteries. We offer maintenance and inspection services.
