Solar Inverter
Solar inverter also know as solar power inverter or solar energy inverter and this the heart of solar power. It is an equipment that converts solar panel’s DC (direct current) power into AC (alternating current) power. This intelligent solar inverter also matches the required frequency, volt etc with electrical grid to run our load to be used at household and commercial premises.
Apart from solar panel, the most important part of any solar system is solar inverter, because it converts power from the sun into useful energy.
Before buying solar inverter, few points should be clear.
- Types – On grid, Off-grid or Hybrid
- Technology – PWM or MPPT
- Feature – Remote Or Web Monitoring
- Brands – Delta, Luminous, Havells
- Warranty – 2 years or 5 years
Types of Solar Inverter
The main roll of all types of solar inverters is to run the connected load on first priority. In the second priority, inverter exports the balance electricity in to battery or Govt. grid. Type of inverter we choose as per situation, grid availability, power cut and load calculation.
Accordingly, solar inverters are classified into three major types:
- On grid solar inverter
- Off grid solar inverter
- Hybrid solar inverter
On Grid Solar Inverter
On grid inverter also called grid tie or grid connected inverters, generally used with on grid solar system. This inverter works with grid or government electricity. On grid solar inverter will continue run your load and send power to the power grid when solar produce extra electricity.
These inverters are fully automatic and intelligent inverter with inbuilt protections which protect the complete solar system and solar panel from any fault. Generally, on grid solar inverter are used for home and commercial use in urban and industrial areas where electricity bills are high.

Other: SMA solar inverter, Solax solar inverter, Sofar solar inverter etc.
Pros & Cons of On Grid Solar
Pros – Advantage
- Utilization of 100% solar power.
- No limitation of load.
- Export extra electricity to grid.
- Up to 70% subsidy on on-grid solar.
- Less space for installation.
Cons – Disadvantage
- Don’t work without grid.
- No electricity generation during power cut.
- No battery back-up.
Off Grid Solar Inverter
Off grid solar inverter also known as stand alone solar inverter or solar battery inverter, are used in off grid solar system. There inverters draw DC power from solar battery & solar panel and convert into usable AC power.
These systems place where no electricity is available such as in rural areas, off grid inverter based system is independent system. The major benefit is that power outages and other technical issues that the utility grid faces will no longer be effective, as you have your own independent power system.
Off Grid Solar Inverter Price
Off grid solar inverter price list for MPPT solar inverters. PWM (old technology) solar prices are less compare to MPPT.
Inverter Model | kW rating | Selling price |
1kW Off grid solar inverter | 1 kW 1P | Rs. 19000 |
2kW Off grid solar inverter | 2 kW 1P | Rs. 25000 |
3kW Off grid solar inverter | 3 kW 1P | Rs. 30000 |
5kW Off grid solar inverter | 5 kW 1P | Rs. 45000 |
6kW Off grid solar inverter | 6 kW 1P | Rs. 75000 |
10kW Off grid solar inverter | 10 kW 1P | Rs. 90000 |
Warranty: Off grid solar inverter has 2 years warranty
Brands in Off Solar Inverter
Pros & Cons of Off Grid Solar
Pros – Advantage
- Stand alone inverter and system.
- Work even without grid/electricity.
- No dependency on govt. electricity.
- Peace of mind with battery backup.
Cons – Disadvantage
- Load limitation
- Cannot export the electricity to grid.
- Costly compare to on grid solar.
Hybrid Solar Inverter
Hybrid inverter is the combination of on grid and off grid solar inverter. This inverter manage solar panel arrays battery storage and utility grid at the same time. These modern all-in-one inverter are generally highly versatile and can be used for grid-tie, stand-alone or backup applications.
Hybrid Solar Inverter Price
Hybrid solar inverter price list for transformer based solar inverters, transformer less solar inverter can be less in price.
Hybrid Inverter Model | kW rating | Selling price |
3kW Hybrid solar inverter | 3 kW 1P | Rs. 75000 |
5kW Hybrid solar inverter | 5 kW 1P | Rs. 78500 |
