Alfa+ Solar PCU 1kVA/24V
Alfa+ Solar PCU 1kVA/24V that is mainly used in Hospitals, schools, industries petrol pumps, banks and also in home. It continuously monitor battery and solar voltage as well as grid and output voltage with their current. PCU (Power Conditioning Unit) is an integrated unit consists of grid charger, inverter, MPPT Solar Charger. It continuously monitors Battery and Solar voltage as well as Grid and Output voltage with their currents.
MPPT based solar charger extracts the maximum power from the solar panels whereby it increases the efficiency of the system. MPPT charger has multistage charging which maintains the battery charging voltage such that it increases the lifespan of battery.

MPPT charger has multistage charging which maintains the battery charging voltage such that it increases the lifespan of the battery.
Alfa+ Solar PCU 1kVA/24V is a Model of Power Conditioning Unit (PCU) which uses Solar (primary) and Grid (secondary), to charge the batteries. Since the usage of power from the grid is secondary, grid power is only used when solar energy is not present and the battery voltage level reduces to 11.5V/Battery (Default 11.5V, Configurable).
Grid power is also needed when solar power generation is less and the battery voltage is reduced to 11.5V/Battery (Default 11.5V, Configurable)
- Battery selection mode
- Operating Mode Selection
- LCD display with Energy Meter and Data Logging (optional)
- Pure sine wave
- User-configurable by LCD
Battery selection mode
In UTL’s Alfa PCU you have a great feature that is battery selection mode by this we can select any type of battery as per requirement i.e Flat plate/Tubular/SMF/Lead-acid Battery and can set charging voltage and charging current as per requirement.
Operating Mode Selection
- PCU Mode – Priority Solar →Battery → Grid
- Smart Mode -Priority Solar → Grid → Battery
- Hybrid Mode – Priority for load Grid →Solar →Battery, Priority for battery charging Solar → Grid
LCD display with Energy Meter and Data Logging (optional)
UTL PCU is also available with LCD. This is an optional feature that can be availed by the customer for the better user interface. When the customer opts for this feature, an Energy Meter and Data Logging facilities are also provided to the customer, which help the user to access information about the present and past status of the PCU functionality. In this way, the user can easily track the past records of the unit and thus he/she can have an idea about what needs to be done for better results.
Pure sine wave
The output of the UTL’s Alfa PCU is a pure sine wave. and it operates your appliances friendly.
User-configurable by LCD
