SOLAR OFF GRID PCU / INVERTER

SOLAR OFF GRID PCU / INVERTER

INTRODUCTION

These are Battery & Solar operated Inverters. SOYO’s Solar Power Conditioning Unit serves both as solar charge controller and inverter. These Inverters are used where there are frequent power failure & usage during night time. It is a unique hybrid system which can charge batteries through solar and grid. As solar panels make DC electricity, it goes to the Solar PCU which converts DC into AC to power electrical load, and stores the remaining DC electricity in batteries. When there is a deficit of solar power, Solar PCU intelligently runs the connected load on solar energy stored in batteries.

1) INTELEGENT CHARGING SHARING ALLOWS YOU TO ENJOY NON-STOP POWER:

PCU is intelligently designed to check the output power of the panels. If the output power is sufficient to charge the battery, then no power is taken from the mains. However, if there is a deficit of solar power, then the remaining will be taken from the mains.


2) DECIDES WHEN TO USE THE GRID :

Soyo has made its off-grid solar inverter, Solar PCU, so intelligent that it can think for you. It always gives priority to solar for running electrical load and uses the rest of solar power for charging of battery bank. It also lets you decide when to connect to grid. If solar panels are not making enough power, it gives you two options: Solar-Mains-Battery and Solar-Battery-Mains


3) IN BUILT SOLAR CHARGE CONTROLLER :

Solar PCU has a built-in charge controller which ensures that right amount of voltage and current reach the battery to charge it efficiently. Solar charge controller also prevents reverse flow of current from batteries to panel during nightime when voltage of battery is more than that of panels.


4) HAVING LCD DISPLAY :

LCD display for indicating various status of the system like inverter voltage, mains voltage, battery voltage, % of load, overload/short circuit status, battery low status, charger status etc.


5) PROTECTIONS :

1) Overload Protection.
2) Short Circuit Protection
3) Battery Deep Discharge Protection
4) Battery Over Charge Protection
5) Mains Over Voltage Protection
6) reverse connection of phase in – phase out Protection
7) reverse connection of phase and neutral of mains input Protection


6) Delayed inverter cutoff for conditions :

like battery low, overload, short circuit etc. The system will automatically restart from cutoff after a few second buzzer beeps. The system will go to permenant cutoff if the error condition exists even after 4 restart.


7) PURE SINE WAVE GIVES YOU ENERGY AND COST EFFICIENCY :

Solar PCU produces pure sine wave; the ideal waveform for the transfer of AC power. Pure Sine Wave, also called as clean electricity, is best suited for health of all AC electrical load such as TV, music system, fridge, fans lights etc.


8) SOLAR POLARITY :

Solar PCU is an intelligent device that always gives preference to solar power and will use Grid/DG power only when the solar power/battery is unable to meet the load requirement.
