Off Grid PCU

Beta N

This product is specially for Nepal...
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.
Beta PCU has the following features:
1. DSP base design built in MPPT solar charge controller.
2. Most advanced LCD features with AC & DC energy meters.(optional)
3. USB/Ethernet based monitoring with 30 days data storage. (optional)
4. Maximum preference to solar. Smart PCU.
5. No load shut down.(optional) By default factory setting-Disable
6. Capability of 100% panel rating.
7. Unity power factor on requirement.
8. Compatible with all PV arrays having different no. of cells.(36 cell/60 cell/72 cell)
9. Tested as per IEC/MNRE parameters. 1-5 KVA MNRE Approved.
10. Single card design more reliable as less wiring is done and has less weight.
11. Lightening protection.
12. All fault display on front panel.
13. High efficiency MPPT and Inverter.
14.1-5 KVA MNRE Approved.
15. No Load Shutdown – Enable / Disable
16. Grid Charger – Enable / Disable 
 

    Battery Health For Longer Life

    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. [Top]

    Extensive electronic protections

    There are a number of protections that the 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 and Overload protection also. [Top]

    Utilizes maximum power available from the panel

    The 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. [Top]

    Computer interface (Optional)

    UTL PCU comes with an additional feature of computer interface. It is an optional feature that can be availed by users who wish to connect their product with a computer to process real time information. This helps in availing advanced features of the product. this feature is highly recommended to the users because the users can derive the best possible results from their product. [Top]

    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 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. [Top]
