Hybrid Inverters
One inverter for grid, solar and battery
The DD-HYBRID series is a 3-in-1 solar inverter / PCU. It runs on-grid, off-grid or hybrid, switches between sources on its own, and keeps shops and homes powered through cuts and low voltage. Six models from 3.8 to 12.1 kVA.
Why customers choose it
Built for patchy grids and tight budgets
Runs when the grid doesn’t
Switches between solar, grid and battery automatically and accepts a 180–265 V grid supply, so shops stay open through power cuts and low voltage.
Works without a battery
Battery-free mode lets a customer start on solar alone and add storage later: a much lower entry price and an easier first purchase.
Sends surplus to the grid
Daytime surplus is exported instead of wasted. Works with lithium and lead-acid banks, so the customer chooses the battery.

Inside the DD-HYBRID
Features that matter on site
- Adaptive energy modes: on-grid, off-grid and hybrid in one unit.
- Maximum solar harvest: MPPT charging (dual MPPT on higher models), pure sine wave output.
- Transformerless, high-frequency build: higher efficiency, lighter and more compact.
- Dual outputs: smart load management across two circuits.
- Built-in BMS communication: RS-485 port for lithium battery packs.
- Remote monitoring: RS-232 port for an external Wi-Fi module.
- Parallel operation for larger loads.
- Made for rural sites: improved dust filter and a larger, clearer display.
How it connects
Solar, grid and battery, managed for you
The inverter decides, moment to moment, which source feeds your loads and where any surplus goes.

Who it is for
Where the DD-HYBRID earns its keep
Kirana, retail & small business
Lights, fans, freezers and billing stay on through cuts; daytime solar cuts the electricity bill.
Homes
Start on solar alone with no battery, then add lithium or lead-acid storage when the budget allows.
Clinics, schools & offices
Dual outputs keep essential circuits on battery while other loads run on solar and grid.
Common questions
Hybrid inverters, answered
Do I need a battery?
No. The DD-HYBRID supports battery-free operation, so you can start on solar and grid only and add a battery later. With a battery, it also keeps your loads running during power cuts.
Which batteries does it work with?
Lithium-ion, lead-acid and SMF batteries. The 3.8 and 4.4 kVA models use a 24 V bank; the 6.6 to 12.1 kVA models use 48 V. Lithium packs communicate with the inverter over the built-in RS-485 BMS port.
Can it send surplus power to the grid?
Yes, daytime surplus can be exported instead of wasted. Exporting to the grid needs a net-metering connection approved by your electricity distribution company; we can guide you through it.
Which model do I need?
It depends on your connected load and how many hours of backup you want. Share your load list or electricity bill with us and we will size the inverter, panels and battery together.
Can I monitor it remotely?
Yes. An external Wi-Fi module connects through the RS-232 port and reports performance data remotely. The front LCD shows running mode, load, input and output on site.
What about warranty and service?
Every unit carries a replacement warranty and is serviced through our Uttar Pradesh service network. Ask us for the warranty terms for your model.
