The sinusPRO S series of solar voltage inverters is used to supply electrical devices requiring 230V alternating voltage from batteries and automotive installations with 24V direct voltage. It can also be successfully used as an backup source of energy for devices that require continuous power, such as heating stove and central heating pumps.

In one housing with a color display there is an automatic voltage regulator AVR, a 30A MPPT solar rectifier for battery charging, a SINUS inverter based on a toroidal transformer, which compensates for different reactive power of receivers (you can combine capacitive, inductive and resistive loads) and reacts very flexibly to overloads (starting pumps, compressors, motors). The inverter can operate in UPS mode, which ensures continuous and trouble-free operation of blowers, feeders, pumps, etc.

The S series has a solid casing designed specifically for hanging on the wall, e.g. in a boiler room or an electrical switchboard, additionally direct access to solar panels, solar / grid operation mode priority switch.

The feature that distinguishes sine inverters from classic simple AC / DC inverters is the production of an alternating voltage with a sinusoidal waveform, identical to that in the power grid. This makes it possible to power devices equipped with electric motors and transformers, such as electric tools, pumps and low-power household appliances. Simple inverters actually produce a square wave voltage. Such voltage is not suitable for supplying inductive or capacitive devices and may damage them.

The most important features:

• rated power (continuous) 1400 W, instantaneous - 2000 VA;
• Input voltage: (battery) 21-30 V DC, (power grid) 140-275 V AC
• generating at the output an alternating voltage with a sinusoidal wave, identical to that in the power grid;
• overloads: switching pulses are largely suppressed by the built-in transformer and the converter is highly resistant to inrush currents, however their exact value is difficult to measure;
• solar regulator 30A 25VDC-50VDC - typical panel voltage 36V (recommended configuration: four panels 250W 36V);
