Large-scale off-grid and hybrid solar and battery installations. Built around Victron Energy and Pylontech technology. Purpose-engineered for farms and rural commercial properties where the grid cannot deliver.
We do not do domestic rooftop solar. Every system is designed around your load profile, your site constraints, and your long-term energy goals.
Complete system design for properties with no viable grid connection. Full Victron architecture with MPPT charge controllers and VRM monitoring, properly sized from day one.
Grid-tied and generator-backed systems with Pylontech lithium battery banks. Reduce diesel dependency and take control of your energy costs without sacrificing reliability.
MultiPlus-II and Quattro installations for commercial loads, dairy operations, and working farm buildings requiring robust three-phase power output.
Hybrid systems designed around your existing diesel generator. Dramatically reduce run hours, fuel consumption, and maintenance costs while retaining backup security.
Properly configured with Victron BMS integration and remote monitoring. Sized to your daily consumption and backup autonomy requirements, with room to scale.
Full technical support for DNO engagement, G99 applications, and grid constraint analysis. If export limitation or grid reinforcement affects your site, we handle it.
