Solar Energy Photovoltaic Home System is suitable for one or more family. It uses a set of new energy technologies device, convert solar energy into electrical energy to solve the home lighting and some basic daily electrical requirements. Its most outstanding value is through a one-time investment and a small amount of self-maintenance costs, you can use for 20 years or even longer; while in use, the family do not need to pay for electricity.

Solar Energy Photovoltaic Home System is suitable for areas far from the city to use, such as: outer suburbs, grasslands, islands, deserts, mountains and so on. In short, it can be used in any place, where has good condition of sunshine. Solar Energy Photovoltaic Home System is also suitable for some relatively fixed work area resident, work teams and groups, observation stations, posts, camps.
Solar Energy Photovoltaic Home System is characterized by high reliability, stable performance, easy installation, easy to operate.

2, Energy storage batteries: solar panels collect solar energy to electricity in the daytime, but power requirements of load may during the day and night, therefore, it need to use energy storage batteries to collect energy in the day time and could supply power at night.

Storage  batteries should match solar panels, at the same time could meet the electricity needs of the load. At present, the storage battery main products are maintenance-free lead-acid battery, gel batteries, iron, lithium batteries, from a cost point of view, maintenance-free lead-acid gel batteries is more economical, its life can reach 3 to 5 years, could be suitable for solar energy photovoltaic home system.

3, Charge controller: It is the key component of solar energy photovoltaic system. A good charge controller, could change battery according to the strength of sunlight. It should make solar energy photovoltaic home system collecting as much energy as possible, that means, charge conversion rate should be high; second is able to change according to the load power, indicating under voltage, over current, short circuit and alarm. Therefore, choosing a good charge control system is important to use.

4,  Inverter devices: output of solar panel is DC power, under normal circumstances, DC can be directly connected to the use of the load; but when there is a need alternating current, it is necessary to convert DC to AC. Inverter output is generally AC 220V or AC 110V.

5,  Display device: show the status of system, it could show input and output voltage / current; if necessary, it could also show input power and power consumption.

6,  applicable socket: According to the general user's requirements, system installed some common access socket can be connected to lights, computers, mobile phones and other electrical loads; also could be based on specific  requirements, install special socket for user.

7,  Cables: the system comes with some installation required cables and wires.
8, the applicable load device: some light source, such as: portability energy-saving lamps, LED lamp.

Solar energy photovoltaic home system is a household power supply, it can be continually used, continuously collect energy from sunlight. the daily storage capacity is relatively limited; Thus, the general design, the input voltage / current, output voltage / current, load power are certain limits. Normally system can be input DC voltage 12V, 24V, input current is generally 5A ~ 10A; its use efficiency can refer to the following formula: the use of load power × time = save electricity Ah × 0.8.
　

1, output overload protection: load power exceeds the maximum output power, the system automatically shuts down;

2, output short circuit protection: Output short-circuit occurred, equipment will be automatically protected, off output;

3, battery polarity reverse protection: battery "+""-" reverse polarity could be continue used after corrected;

4, Battery Over-Discharge protection: Battery Voltage is below 10.8V (12V system) / 21.6V (24V system), There is no output, voltage indicator light; when the battery voltage is higher than 11.2V (12V system)/22.5V(24V System), the output restart.

5, Over-charging protection: battery voltage is below 13.2V (12V system)/ 26.5V (24V system), battery will be charged in float charging status; when the battery voltage is 15V (12V system)/31.2V (24V system), solar panel will be completely shut down charging that this is overcharge protection; when the battery voltage discharge to 13.2V (12V system)/ 26.5V ( 24V system), resume charging.

6, solar panel reverse protection: solar panel "+""-" reversed polarity, there is anti-reverse circuit, , may continue using after corrected .

7, lightning protection: close the main control box input switch, can protect against lightning.

8.Power supply capability

The system uses PWM Pulse modulation, combined with real-time MPPT convert the Solar Energy with high efficiency charging battery; charging has low voltage, fast charge, float charge, over-charging, stop charging five kinds of status. Different status with charging current; in float charging the system will enter a cycle of decreasing current charging; in over-charging the system will enter a cycle with a very small trickle charge current, in order to compensate for battery self-discharge and insure the maximum battery energy storage.

The system has external temperature sensor to measure the ambient temperature in real time in order to correct the battery temperature compensation, the compensation coefficient-3.84Mv / ℃ / cell, ensure the battery not over charged or not fully charged due to environmental temperature, ensuring the battery life.

When the LED indicator is green, means inverter switch is on, at this time could supply 220V AC output. If the battery voltage is below 21.6V (25 ℃ when the value; ambient temperature changes, this value is automatically corrected), the system will automatically turn off inverter, in order to protect the storage battery from being over-discharged; the same time, the green indicator does not shine (even if the inverter switch on the ON position, can not open the inverter). When the storage battery voltage is higher than the opening voltage of the load, the system will automatically open the power inverter (power inverter switch must be on the ON position) then output alternating current.

② When the LED indicator is red, indicating the load in a fed power state, power supply is insufficient and needs to shut down the load. The load in the fed power state, there are two cause, one is the system load power exceeds the maximum power requirements, in this case load must be replaced under rated power; the other cause is the system used too much, stored energy is not enough, let the system continue to charge, over a period of time, you can connect the load to use.

③ In the system, installed fuse for the inverter, used to protect the storage batteries and other devices from outside impact of high current. When the AC load exceeds the design requirements (≥ 160W), system will automatically shut down inverter; reduce the AC load power requirements(≤ 150W) could restart AC power.

1,clean solar panel’s surface regularly, in order to get a better power output.
2, check system state regularly,  in order to maintain the system functions well.
