The weaterproofed SAJ R5 inverters are optimal for residential rooftop solar power systems. The series includes single-phase devices from 3kW to 8kW and three-phase inverters from 3kW to 20kW. As a result, the biggest models of the R5 series are powerful enough to supply a full family household or small-scale business.
The R5 series reaches a maximum efficiency of 98.8%. Consequently, R5 inverters are among the most efficient in the industry. Overload capacities of 110% and 150% for significantly higher power generation. Furthermore, 24h load consumption monitoring allows users to monitor the performance of the solar PV system at all times.
The R5 inverters are equipped with a robust city cooling system based on natural convection. As a result, they stand out with a service life of up to 25 years and noise levels are kept to a minimum. Lastly, a die-casting casing design gives the R5 a better heat dissipating performance.

The H1 is a hybrid inverter designed to convert both current and charge a battery. All models of the series are available in power classes from 3 kW to 6 kW. Therefore, the H1 is particularly suitable for small to medium-sized systems in residential areas.
The H1 is designed to operate in island mode, allowing the inverter to work even during power outages. In addition, different working modes can be set as per different customer needs.
It charges solar batteries with a voltage range of 42V to 58.5V. The larger models achieve maximum charging currents of 100A. Therefore, the H1 is a great device for quick charging.
With wattages of up to 6 kW, H1 inverters can handle up to 15 panels. In addition, two MPPT circuits ensure maximum performance.

The inverter converts DC to AC power for consumption by households and businesses © Clean Energy Reviews
A solar panel string inverter converts DC electric current of solar panels into alternating current (AC). As seen in this diagram, it is the final piece of a PV system. From there, the electricity gets transmitted to end devices for consumption.
IThe inverter must at least be able to handle the maximum power that the solar power system can produce. For example, a 9kW system with 30 300 watt solar panels needs a 9kW inverter. However, due to system losses in the modules, the nominal power of the inverter may in some cases be up to 25% lower than that of the solar panel array. Long-lasting systems require a high quality inverter with a robust convection cooling system.
Generally, inverters are sensitive electronic devices, producing thousands of watts for up to 10 hours per day. The better protected it is from heat and weather, the better it will perform and the longer it will last. Furthermore, it may be a warranty condition that the device is not installed in a location where it is exposed to direct sunlight. Therefore, it is important to use a high-quality inverter with weatherproofing.
Most grid tie inverters are weatherproof (IP65 protection), allowing for deployment in open areas. Non-weatherproofed inverters require the installation of a weatherproof cage (at an additional cost) for deployment in exposed places.
In many cases, a solar inverters malfunction is not hardware-related. Therefore, the solar inverter fault codes in the device manual and the error message on the monitoring display should be checked first.
Some manufacturers (like SAJ) offer a “5 + 5” year warranty where parts and labor are covered for the first 5 years. Generally, it is highly recommended to find out about the warranty on the device and weigh it against other features of the solar power system to make an informed decision about what inverter best suits your needs.
A combination of high-quality materials and state-of-the-art cooling systems makes SAJ inverters excel with a service life of up to 25 years. As a commitment to our high quality standards, you receive a warranty* on every SAJ inverter you buy from us.
All costs that may occur during this time will be covered by us, including free solar inverter replacement and repair.
When buying a complete system, the cost of inverters usually only accounts for between 10 and 20 %. Therefore, it is investing in a high-quality inverter, as it has a major impact on the efficiency and performance of your solar power project.
Our team of expert engineers provides you with free online consultation to help you determine the most efficient equipment choice.
*We provide a 10-year standard warranty program for R5 series and a 5-year standard warranty program for H1 series. Additional years of warranty (up to 20) can be purchased with a rebate within the first 18 months after purchase.
SAJ devices are renowned for their long service-life and reliability while keeping prices to a minimum. Consequently, SAJ is a popular brand for commercial and residential solar power plants in industrial countries. However, SAJ also established a name for itself leading a number of povery alleviation projects in developing countries.

A high-quality solar panel inverter is an essential part of your system and should be located in an easily accessible place. It serves two functions:
Most inverters now have internet connectivity to allow for remote control.
The quickest way to find out the required number of solar panels for your system is to use our solar power calculator. All you need to know is your average monthly utility bill.
Optimizers enable modular solar system designs and configurations - with multiple panel orientations, tilts, azimuths and module types in a given series. Thus, a system with panel optimizers yields a higher device output because it bypasses the 'lowest common denominator' effect of shaded panels. Although an optimizer inverter system may be slightly more expensive than a string inverter system, the financial gains from increased energy production outweigh the additional cost and are generally worth the investment if your solar project site has multiple azimuths, is tilted or shaded.
Yes, you can use solar power to charge your electric car just as you can power the rest of your household devices with it. Even a small solar system with only 10 solar panels can provide enough power to charge your car's battery.
