Enertech has specialized in solar online UPS for industrial purposes. The inverter has been  designed in such a way that it fits different industrial purposes. The solar UPS has been created perfectly with the highest efficiency. Its pure sine wave output allows it to be suitable for industrial equipment and high-end electronics. The solar UPS allows uninterrupted electricity for a long time, as the load is kept constant and has approximately zero change over time. We have combined the highest level technology like distance working along with interactive front LED display for efficient performance.

Working of Solar Online UPS      

The solar UPS has a grid frequency of 50Hz ± 6% and a selectable chargeable battery of 50 A to 200 A. The solar online UPS allows continuous electricity to heavy machines and industries. The solar panels in the inverter rely on sunlight and provide the much-required electricity. The MPPT based solar UPS has 2 MPPT modes and works smoothly in all equipment with the best battery support. They have a good inbuilt galvanic isolation transformer and peak efficiency higher than 75%.

The IGBT-based Solar Online UPS can handle industrial overload up to 125% for sixty seconds and 150% for five seconds. It can also be customized as per the requirement and also for varying load capacity. Its unique LED display shows different parameters of voltage, frequency, input GRP, and current.

The output frequency of 50hZ makes the solar online UPS a perfect choice for industrial purposes. The modes available for configuration are- grid export mode, VFD mode, and AC mode. The solar UPS is a perfect option for industries as it also works in extreme conditions and has an operating temperature of 0 to 40 degrees Celcius. They are also capable of working in rugged areas.

The EnerTech Solar online UPS functions with less than 65 dB acoustic noise level. The UPS can also work in relative humidity of up to 95%. Solar online UPS also has a buffer battery for emergency backup. The solar UPS priority is user-selectable and can be switched from solar to battery. These UPS can be controlled remotely using MODBUS, Ethernet, and RS232.
