UTL Sigma Grid Export Solar PCU 1 Kva 48V Price

Sigma+ PCU is a solar power conditioning unit which is a single phase output, Inverter system. It works as a Bi-directional inverter which means power will be exported into the grid or power will be imported from the Grid.

The Sigma+ PCU work in two operating condition:
1. Stand-alone
2. Grid Interactive

Stand-alone: Inverter operates from battery or array power source and produces AC output. Battery charged by solar (primary) & also from grid (secondary). Since usage of power from grid is secondary, grid power is only used when solar power is absent or below a certain level and battery voltage level reduces upto battery low status. Working Modes: Smart, PCU & Hybrid

Grid Interactive: Inverter operates from battery or array power source and produces AC output and also operates in parallel with the grid supply. Any excess solar power will be exported into the grid. Whenever sufficient solar power is not available to run the load, the required power is shared from the grid. The maximum power feed into the grid is depends on the system rating. Battery charging automatically occur from the grid to maintain the battery bank at its grid charging voltage. Working Modes: Grid Export Mode

Grid High/recover 280/275 V
Synchronization voltage range 185/280 V
Synchronization frequency range 47 to 53 V
maximum charging current from grid (import) 1-15 A

Battery

The PCU feeds the battery installed to it a constant boost charging current until its voltage reaches 14.2V and the float current (which is very close to zero) then maintains this voltage above 13V. Thus reducing the float current ( flowing for the longest period during the entire process) to zero, ultimately resulting in much enhanced battery life keeping it fully charged simultaneously.
