The original Stäubli MC4 photovoltaic connectors for reliable DC connections between panels and strings.
Stäubli's MC4 connectors (PV-KBT4 female and PV-KST4 male) are the original MC4 photovoltaic connectors. Reliable connectors are essential for safety: poor or mismatched connectors are a common cause of faults and overheating in solar systems.
Current ratings depend on the cable cross-section and the standard used, so the connector must be matched to the cable. Stäubli also offers newer MC4-Evo connectors rated for 1500 V systems.

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.
