Best Off Grid Solar Inverters in Sri Lanka
On-grid and off-grid are the two most common types of solar systems. On-grid means that all the components of your system must be connected to the grid. Off-grid means that you have your own power generation system, but it may or may not be connected to the grid. Each has its benefits, but if you want to get into solar it's important that you understand what each system entails so that you can choose which one is right for your home or business.
What is a Solar System?
A solar system is an arrangement that uses solar energy to create electricity. A typical solar system includes of-
- solar panels - which collect sunlight
- solar inverter - which converts DC to AC
- a mounting frame - which holds the panels in place
- batteries - which store excess electricity
- a grid box
- and system balancing (wires, nuts etc.).
How can we use Solar Energy?
All solar power systemsoperate on the same fundamental principles. Solar panels use the photovoltaic (PV) effect to convert solar energy or sunlight into direct current (DC) power. The DC electricity may either be stored in a battery or transformed into AC power by a solar converter, which can then be utilised to power household appliances. Excess solar energy can be delivered into the power grid for credits or stored in a number of different battery storage devices, depending on the kind of installation. A solar system can be 1 kWh, 2 kWh, 3kW, 5kW, 7.5 kW, or 10kW in size. On average, a house with monthly electricity consumption of 1000 kWh requires 26 – 30 solar panels (Each solar panel is 320 watt).
Solar system price- Installing a solar system for a homeis Rs. 25,000 if you already have a single inverter battery and Rs. 50,000 if you already have a double inverter battery.
The three main types of solar systems are-
- On-grid solar system - also known as a grid-tie or grid-feed solar system
- Off-grid solar system - also known as a stand-alone power system (SAPS)
- Hybrid solar system - grid-connected solar system with battery storage
Uses of Solar energy
- Solar heating can be used for swimming pools.
- Solar water heater
- Heating of an entire house with the help of solar energy
- Charging of batteries with solar power.
- Power the entire house with solar energy
- Solar energy can be used for cooking
- Outdoor lightning
- Solar power pumps
What is an on grid and off grid solar system?
On-grid and off-grid are the two most common types of solar systems. On-grid means that all the components of your system must be connected to the grid. Off-grid means that you have your own power generation system, but it may or may not be connected to the grid. Each has its benefits, but if you want to get into solar it's important that you understand what each system entails so that you can choose which one is right for your home or business.
On grid solar system- An on-grid or grid-tied solar system is one that operates in tandem with the power grid. This implies that any surplus or deficit in electricity may be supplied back into the grid via net metering. Many household users are choosing an On-grid solar system since they may receive credit for the extra power produced by their system and save money on their electricity bills. You will always have access to power, whether from the solar system or the grid. They are not powered by batteries.
Off grid solar system - Off-grid solar systems operate independently of the grid but include batteries that can store the solar power generated and supply electricity after the power goes off or during the night.
Off-grid solar systems must be properly built in order to generate enough electricity throughout the year and have enough battery capacity to satisfy the needs of the residents, even in the dead of winter when there is often significantly less sunshine.
What is the difference between an off-grid and on-grid solar system?
The main differences between off-grid and on-grid solar systems are-
- An Off-Grid solar system will continue to operate even if power is lost, however, an On-Grid system would not.
- A grid-connected solar system is less costly than an off-grid solar system.
- An off-grid solar energy system is not tied to the utility grid, but an on-grid (also known as grid-tied) solar energy system is.
- If your PV system is not connected to the grid, you will not receive an electric bill. Even though your solar system generates 100 per cent of your power, if you choose a grid-tied system, you may still notice a few minor costs on your electricity statement.
Here are a few fundamental things to consider when purchasing a solar inverter for your house or business:

Best Off Grid Solar Inverters in Sri Lanka 2023
- LENTO - Lento pioneered pure Sine wave technology in its inverters, UPS and power supplies. The Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipments, especially inductive loads that do not work well on square waves. Most appliances like CFL, fans, motor based equipments like air conditioners and pump sets are designed to work on 50 Hz sine wave. Running such equipments on unregulated quasi sine wave-square wave based inverters poses a risk as regards performance and durability. Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, our inverters and UPS are designed to deliver instantaneous high current during start up, especially in case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.
An Auto sense intelligent control smart charger and electronic changeover, hence much better reliability. It conducts the quiet operation of AC motors as well as other inductive loads, unlike the noise that emanates from Modified Sine Wave Systems. It gives more accurate readings and reduced errors. Requires less energy consumption as compared to modified sine wave systems. Is able to run a wide range of appliances including computers/laptops, CFLS and other sensitive electronic devices. It also provides better voltage regulation and less fluctuation, hence a more stable power supply. It is environmentally friendly.
- Product Name - Solar hybrid domestic inverter / PCU (MPPT Type) - Lento offers next generation smart MPPT based solar chargers for maximum efficiency and highest performance required in demanding situation. MPPT stands for maximum power point tracking and Lento’s smart MPPT solar chargers play a crucial, central role in stand alone and hybrid solar power installation. MPPT increases energy transfer efficiency by as much as 30% by calculating maximum voltage available from the SPV modules at which maximum power is available for charging and sets the charging current accordingly. Output from SPV modules can vary considerably according to changing weather conditions and incorporation of MPPT means the charging conditions are always optimized by covering extra voltage to amperes and thus speeding up the charging process. Lento uses high grade components to assure best performance and extended life of the unit.

Frequently Asked Questions-
Q. How do I choose a solar inverter?
As a general rule of thumb, the size of your inverter should be similar to the DC rating of your solar panel system; if you are installing a 6 kilowatt (kW) system, you can expect the proposed inverter to be around 6000 W, plus or minus a small percentage.
Q. What voltage is best for off-grid?
2 Use the highest system voltage for off-grid solar systems. Most people start exploring off-grid solar systems with the system voltage of 12 volts. 12 volts is very common, and that makes things easy because there are lots of choices of batteries, inverters, chargers, and devices such as light bulbs that can use 12VDC.
Q. Can I use solar without inverter?
No, the current solar panel is only effective at converting sunlight into electricity. A built-in inverter is needed to turn the direct current (DC) from solar panels into alternating current (AC) and supply power to the whole household.
