PCU2

STATCON POWTECH ‘Off Grid’ series of Single Phase PCU are designed to meet the growing electricity demand of developing countries. The state of art design and intelligent control optimizes the yield of all small and medium level PV plant.

STATCON POWTECH ‘Off Grid PCU’ consist of ‘MPPT’ based charge controller and bi-directional inverter with a transformer on AC side. It provides uninterrupted power to the load using solar, battery and grid input in same order of priority. In-house developed latest DSP based pure sine wave technology ensures excellent performance, protection from any kind of malfunction and the high conversion efficiency is achieved. The high conversion efficiency helps in longer battery backup. Ease of operation and plug & play type of design make it an ideal product for all uses. These ‘Off Grid PCU’ are capable of being configured for priority of solar, battery or grid as described below:

SALIENT FEATURES

When solar energy is sufficient then the output of MPPT charges the batteries along with feeding inverter to produce AC to meet load demand. If solar is not sufficient to charge the battery then both MPPT charger and grid charger charges the battery, in this condition max. power yields from solar to charge the battery.

BATTERY PRIORITY

When MPPT is not sufficient to meet load demand then the combination of MPPT output and batteries are used to feed an inverter to produce AC to meet load demand.

MAINS AT PRIORITY

If the battery has low voltage condition then the load is shifted to grid and batteries are charged through MPPT. If MPPT is not available to charge batteries then grid charger becomes active to charge batteries and load is fed from a grid. Once the batteries are fully charged the load is automatically shifted on solar and batteries.

Statcon Powtech PCU with higher rated MPPT is available on demand. Statcon Powtech also offers ‘Off Grid PCU’ for welding sets. Statcon Powtech Pump Combo Series is capable of working with DC Pump, utilizing same solar panels installed for DC pumps.

SALIENT FEATURES
  • Excellent yield from solar through MPPT based charger controller.
  • Rapid charging in minimum time through mains charger.
  • Suited for all battery types.
  • High efficiency at full/half loads.
  • Galvanic isolation on AC side.
  • 3 stage battery charging, current limiting, temp.compensation.
  • Excellent performance up to 50 degrees of temperature.
  • Digital display with fault & energy logging.
  • Remote monitoring over internet & RS 485.
  • Available in different capacities & battery voltages.
  • Various modes of operation to suit all types of users.
