Battery is in the state of charge and discharge, large amount of sunshine in the summer, not only supply the power to the load, but also charge for battery. Less amount of sunshine in the winter, will release the stored energy gradual.

In the daytime, the solar panel will charge for battery and supply the power to load at the same time. In the night, the power all supply from battery. Do you want to know what the power you use? Want to know how much consumption you use? Want to know how many power saving by the solar system.

Blue Jay Power Analyzer can do all these things measure power usage throughout the day and at any time, measure solar output, through day and total day, week, month, tell you each day what you have been charged by retailer and what retailer will credit you each day and totally.

When in the house using, will have an inverter, because the direct output of solar system is 12VDC, 24VDC, 48VDC, in order to supply the 220VAC electric equipment. Need to transmit the DC power to the AC power.

Although there is a simple panel meter to display the output current and voltage. But in fact the customer doesn't know clearly how many power they use. Blue Jay Power Analyzer can measure the exact energy, active power, power factor generated by solar systems. Also can detect the power factor of inverter, and the power consumption of the whole grid. So that you can know the real power generate by system. If the solar system generate exceed energy, you can sold it to the power company. When the electricity is not enough to use, you can buy it from Power Company. Blue Jay Power Analyzer also can faithful record the sold and purchase energy, from the Analyzer software, you can know the billing clearly.

The specially thing of Blue Jay Power Analyzer is when you turn a set of lights ON or OFF, you can see instantly the change this has to your energy use. Once you have this information to hand means you, your family, or business, can visually see the benefits of saving energy.

Some countries will let the grid to collect all customers' power data via meters, then further statistics and analysis the data. This system named Energy Consumption Management Analysis System. It is based on the computer, communications equipment, and control unit as the basic tool, according the actual situation to combine the most optimized network. Our Blue Jay power analyzer can maximum connects 247 units, and can connect to supply network, transmit the data to the servers or PC via internet. It is suit for multi-user areas which generate power by themselves, school or other large public buildings, so that the power companies can management the data convenient, and do the further analysis. This not only saves natural resources, but also saves the human resources.


The power measurement system is an ideal tool for monitoring power consumption especially in large-scale public buildings. Adopting advanced technology, it is more intelligent, automatic, and great reducing man power. With power measurement system installed, your building must be in effective management of both energy and human resources. With power measurement system installed, you can easily get the information how much energy consumption every day. With it, you can get payback of energy saving and man power reducing in a short time.

Power Measurement System

Located at center room, main control system contains an advanced computer and other settings as UPS, printer and alarm. Power measurement software is monitoring and controlling the whole electrical equipments.

In middle of level one and level three, communication system transforms digital information from site equipments measurement level to station management level. It improves the whole system to be more real-time, larger capable. Additionally, this system can share the data information by easily connecting with other systems though Ethernet switches.

Using panel meters and DIN-rail meters, site monitor system is monitoring and measuring electrical parameters of all site equipments. With RS458 communication, this system transmits various electrical parameters and signals to communication level. All these devices work independently.

The power measurement system contains three levels according to function features:
Level one — main control system (station management level )
Level two — communication system (Internet communication level)
Level three — site monitor system ( site equipments measurement level)Level one Level two Level three
