This DC-coupled system can form its own grid, switching between grid-tied and off-grid operation so power stays on even when the grid drops. DC coupling raises battery charging efficiency and allows more installable PV capacity, and external multi-channel PV MPPT replaces conventional combiner boxes for a simpler, more flexible layout — suited to off-grid, weak-grid and diesel-hybrid sites.

DC-Coupled Grid-Forming PV-Storage Hybrid System
Grid-forming / off-grid (PV-storage-diesel)
1 / 2
Overview
A DC-coupled grid-forming / off-grid PV-storage system (PV-storage-diesel hybrid) offering seamless switchover to off-grid operation without loss of power, higher DC-coupled charging efficiency, larger installable PV capacity and external multi-channel PV MPPT in place of combiner boxes.
Entogo, a Canadian company, builds the DC-Coupled Grid-Forming PV-Storage Hybrid System in its own factory in China with a vertically integrated supply chain — factory-direct pricing, shipping in 16–24 weeks (within 36 weeks when the order needs new cULus/CSA certification), and a minimum 36-month manufacturer warranty backed by Entogo Inc. in Toronto.
Key features
- Grid-tied / off-grid switching — "grid-off but not power-off".
- DC coupling raises battery charging efficiency.
- Greater installable PV capacity than AC-coupled designs.
- External multi-channel PV MPPT replaces conventional combiner boxes.
