An on-grid solar inverter converts the DC electricity from solar panels into AC electricity your home and the grid can use. It also finds the best operating point of the panels, keeps in step with the grid, shuts down safely if the grid fails, and records how much you generate.
Its five main jobs
- Convert DC to AC: panels produce direct current; homes and the grid use alternating current.
- Track maximum power (MPPT): it constantly adjusts to get the most from the panels as sunlight changes.
- Match the grid: it synchronises voltage and frequency with the grid supply.
- Protect: it stops exporting if the grid fails (anti-islanding) and guards against faults.
- Monitor: it records generation and faults, viewable on its display or an app.
What should I look for?
- A size that matches your panels and connection.
- High efficiency.
- A suitable enclosure rating (for example IP65 for outdoor mounting).
- BIS registration for Indian grid standards.
- A clear warranty and local service.
Tenzor’s on-grid range
The Supernova 1-Phase covers 1 to 6 kW for single-phase connections; the Supernova 3-Phase covers 5 to 15 kW for three-phase. Both are IP65 rated, BIS registered (R-91022799) and carry an 8-year product warranty and a 10-year performance warranty, running concurrently.
FAQs
Is an on-grid inverter the same as a home UPS inverter?
No. A home UPS charges batteries from the grid. An on-grid solar inverter converts solar power and feeds it to your loads and the grid.
Does an on-grid inverter need batteries?
No. For battery backup, use a hybrid inverter such as the Tenzor Hypernova.
