⚠ Important note about grid charging (NO GRID CHARGER)

This kit is supplied without a separate grid battery charger.

• If your design requires grid-assisted battery charging while keeping the inverter on a maintained/off-grid board, a suitable charger can be added separately.

• If the inverter is configured as a grid-connected/exporting system, DNO requirements may apply.

• If the system is wired/configured to be fully islanded with no export path, it can be operated without grid export approval.

• Free delivery

• Grid charger not included

📌 Final disclaimer

Final system suitability depends on installation layout, roof space, shading, load profile, and wiring design. If you are unsure whether this kit is appropriate for your site, please contact us before ordering.

These systems are designed to run large electrical loads without exporting to the grid, avoiding DNO export approval.
Battery charging is provided via a dedicated 100A or 300A DC battery charger, allowing the grid or generator to support charging while the inverter supplies all loads from a maintained circuit.

Battery charger options

• 100A charger

  • Overnight recovery

  • Smaller farms / lighter winter use

  • Generator-friendly

• 300A charger

  • Fast recovery after heavy use

  • Larger farms

  • Minimises generator runtime

  • Better for winter resilience

Charger size depends on daily energy use and how quickly batteries need to recover.
