Solar Off Grid PWM PCU

CLEAN & GREEN SOLAR POWER BACKUP

Electrower's Off Grid PMW Solar PCU (Power Conditioning Unit) is an intelligent integrated system of Solar PWM Charger, Grid Charger, Offline InverterWe use innovative PWM algorithmin our Solar Off-Grid PCU that can simultaneously run the load and charge the battery while extracting power from Solar, although it is less efficient than MPPT technique of charging. Suitable for standard Lead-Acid Batteries, as well as flooded, sealed and Lithium type. Our Solar Off-Grid PWM PCU stand apart from the rest because of their high-quality design and multiple features we have packed into it to make your life easier.

INVERTER SWITCH

Push to On and push to Off switch. Whenever this switch is On, the Inverter will automatically turn on, until any unavoidable fault occurs. If the fault is recovered, the inverter will automatically switch on. 


16X2 ALPHANUMERIC DISPLAY

display to show all parameters related to Inverter, Battery and Mains. Also, display the system internal parameters and status. It helps the electrician and service engineer to easily diagnose the problem.


LED INDICATION

5 LEDs, UPS, Charging, Mains, Battery, Overload are given to easily identify the state of the system and diagnose the fault. 


INVERTER SWITCH

Push to On and push to Off switch. Whenever this switch is On, the Inverter will automatically turn on, until any unavoidable fault occurs. If the fault is recovered in case of static bypass, the inverter will automatically switch on. 


20X4 ALPHANUMERIC DISPLAY

Big display to show all parameters related to Inverter, Battery and Mains. Also, display the system internal parameters and status. It helps the electrician and service engineer to easily diagnose the problem.

How it works?

Electrower's Solar Off-Grid PWM PCU consists of a PWM Solar Charge Controller, Offline Inverter, and a Grid Charger all in an integrated form. The Off-Grid Solar PCU is designed to maximise the use of Solar Power. When the batteries are charged from Solar, the Smart PCU disconnects Grid/Mains/DG and let the Inverter/Load run on Solar. It let user enhance use of solar power, also as per the user preferences it has twpmodes:

  • Smart Mode (PCU gives priority to solar, second priority to the grid and third priority to the batteries in smart mode). Recommended in Semi-Urban Area, where power cut is less than 2 hours.
  • Hybrid Mode (In this mode PCU works well with solar as well as batteries. Grid charging only takes place when solar power is not sufficient to charge the batteries). Recommended in Rural Area, where power cut is more than 2-3 hours.

Available Models

SUNRAY E-SINE

  • Available from 850VA/12V to 5KVA/48V Models.
  • Can be turned ON by Mains, It can turn on battery from 0 volts. 
  • It is highly recommended for Home use & Shops.
