Conversol Off Grid Solar Inverter 3kVA - 110VAC/120VAC

Parallel Ready Unit up to 6 inverters

Conversol is the most cost-effective, easy-to-use, and versatile solar inverter in the solar industry. With an integrate battery charger and advanced microprocessor that allows for easy digital control implementation, Conversol provides reliable power conversion in a compact but robust unit. Thanks to its low “no load” current, the inverter offers a relatively long battery life that exceeds that of other products of its kind. Extreme peak power capability enables high loads to start up easily without power dips or light flickering. What’s more, Conversol has been designed to operate in a wide range of temperature conditions, from -20°C to +50°C, which makes it a superior solar inverter that’s unmatched in the industry.

Conversol is part of Voltacon’s complete off-grid solutions that includes solar panels, cables, fuses, automation, and of course the widest range of solar off grid inverters known to the solar industry.

Suitable for the US Market - 110V/120VAC AC Output

Conversol is an intelligent combi solar inverter that comes with integrated battery charger that is enclosed within a robust quality unit that’s easy to install. Control is easily implemented digitally thanks to its advanced microprocessor, while its transformerless design ensures you of reliable power conversion. Designed for a wide range of operating temperatures, from -20°C to +50°C, Conversol works even in the most demanding conditions, which makes it the most easy-to-use and cost-effective solar inverter on the market.

Affordable Autonomous Power Supply

The 3kVA (2400W) off-grid inverter comes with a powerful, ultra-fast charger with MPPT tracking algorithm. The charging current is selectable in 20A, 30A and 60A. The batteries can be charged from solar panels and utility power supply. The utility AC input can be the public grid or a sinewave diesel generator. 

The low "no-load" current the battery from draining fast. Extreme power peak capability allows high current loads to start up easily without power dips or light flickering.

Typical Configurations

  • Off Grid autonomous single or three phase with PV Solar as main charging source
  • Off Grid autonomous singe or three phase with AC back up (generator) and Photovoltaic panels
  • Off Grid opertion with AC generator only. 

Compatible AC Loads and Appliances

The product can be directly connected to various motor-type loads like refrigerators, pumps, laser printers, and motors. You can power up any domestic appliances such as vaccum cleaners, microwave, washing machines, blow driers, lights and ovens. Voltacon’s Conversol inverters include an unbeatable 2-year warranty, plus monitoring software. You can now generate your own electricity and live a comfortable life without spending a fortune!

AC Input : Connection to Generator or AC Grid
  • The generator should be size 1.5 time the power rating of the inverter for smooth and stable operation. It is also recommended to use overiszed generator to reduce the risk for of overloading.
  • Inverter-generator and pure sine wave gen-sets are recommended. Generators with modified sine wave output are not suitable.

Customer Reviews

easy installation pure sinewave at 3kW Review by PR
Very satisfied it was delivered to Puerto Rico quickly and i had technical support (Posted on 6/13/2019)
The best in Puerto RICO Review by Carlos P.
I bought this as the only compatible solution for my country (Puerto Rico), and very affordable price.

I might put another one in parallel in the future.

There are instruction in the box, very easy to set it up

3 in parallel Review by Dan
I have already set up 3 of these inverter in USA, they all communicate well with the special parallel kit.

I withdraw up to 6-7kw , the pick power can reach 9kW all as a single phase system. The 110VAC output is stable and pure sinewave

Best Unit for the money you can get Review by John
I now own 2 of these units and they work very well single and paired, they are in daily use with good loads.
The only complaint is that the software for the units do not have an option to change the chargers behavior based on time of day.
for the small system with a small battery it need to know that the sun is setting and change to mains power before it starts to kill the battery dead every night as the power from the sun gets less.
this will shorten the life of the battery, it has this problem as sunrise as well, for the 1st hour and half each morning and last hr each night it should switch to charge battery with light and run house on mains.
That being said, all other aspect meet or exceed expectations!
I run 2 to 3 kw all day with this system. It was easy to set up. Easy to configure. And has most all the features one would want or need. I am a very happy customer and have been running for more than half a year.
All that said this is the best unit for the $$$$ you could hope to find and I tried a alot of them. (Posted on 1/26/2018)
