UTL Gamma Solar PCU 3KVA 48V Price Specification

Gamma PCU is a Solar Power Conditioning Unit (PCU) which uses Solar energy (primary) and also the power from grid (secondary), to charge the batteries. Since usage of power from grid is secondary, grid power is only used when solar energy is not present and battery voltage level reduces to a certain level. Grid power is also needed when solar power is reduced to a certain level and battery voltage is reduced to a certain level.

GAMMA PCU has the following advance features like DSP base design built in MPPT solar charge controller. , Most advanced LCD features. , Maximum preference to solar. Smart PCU , Capability of 100% panel rating. , Compatible with all PV arrays having different no. of cells.(36 cell/60 cell/72 cell). , Lightning protection . High efficiency MPPT and Inverter.

Battery Health For Longer Life : Gamma 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.

Extensive electronic protections : There are a number of protections that Gamma PCU ensures. It stops reverse current flow from battery to solar array, it provides load short circuit protection, it provides Battery/Panel reverse protection through DC fuse,Overload protection, Input low/High, Output Low/High.

Utilizes maximum power available from the panel : Gamma PCU senses the point of maximum power available in the panel and charges the battery with this maximum power. Therefore, the battery is always charged with maximum possible power at any given time. This is the feature that allows your device to work to its full capacity and thus deliver the best possible results.

LCD display : Gamma PCU is available with LCD, for better user interface. It shows Battery voltage, charging current, discharging current, Output voltage , Output frequency, Output load percentage, Input voltage, Input frequency, Solar voltage, Solar current & Solar Power. It has for switches to configure Operational mode, No load shut down, Grid charger, IT Load, Input source.
