Domestic solar panel

- Jun 24, 2019-

Household solar panels are the core part of the solar power generation system. The role of solar panels is to convert the sun's light energy into electricity, output direct current and store it in the battery. Solar panel is one of the most important components of domestic solar power generation.

Introduction:

Household solar panels are the core part of solar power generation system, the role of solar panels is to convert the sun's light energy into electricity, transmission.

Direct current is stored in the battery. Solar panel is one of the most important components of domestic solar power generation. Module design: according to IEC: 1215:1993, 36 or 72 polysilicon solar cells are used in series to form 12V and 24V modules of various types. The module can be used in various household photovoltaic systems, independent photovoltaic power stations and grid-connected photovoltaic power stations. 

Solar controller

Solar controller is composed of special processor CPU, electronic components, display, switch power tube and so on.

The main features:

1, the use of single-chip microcomputer and special software, to achieve intelligent control;

2, the use of battery discharge rate characteristics of accurate discharge control. The voltage at the end of discharge is a control point modified by the discharge rate curve, which eliminates the inaccuracy of simple voltage control overdischarge, and conforms to the inherent characteristics of the battery, that is, different discharge rates have different end voltage.

3, with overcharge, overdischarge, electronic short circuit, overload protection, unique anti-reverse connection protection and other automatic control; The above protection does not damage any parts, does not burn insurance;

4, the use of a series of PWM charging main circuit, the voltage loss of the charging circuit is reduced by nearly half than the use of diode charging circuit, charging efficiency is higher than non-pwm 3% to 6%, increased the time of electricity consumption; Overdischarge recovery of the lifting charge, normal direct charge, floating charge automatic control mode to make the system from a longer service life; At the same time, it has high precision temperature compensation.

5, intuitive LED LED indicator current battery state, so that users understand the use of the situation;

6. All controls are industrial grade chip (only industrial grade controller with I), which can operate freely in cold, high temperature and humid environment. At the same time, crystal oscillator timing control is used.

7. The set point of potentiometer adjustment and control is cancelled, and e-square memory is used to record all working control points, so that the setting is digitized, eliminating the factors that may cause errors of control points to reduce accuracy and reliability due to potentiometer vibration deviation and temperature drift, etc.;

8, the use of digital LED display and Settings, one-click operation can complete all the Settings, the use of extremely convenient and intuitive function is to control the working state of the whole system, and the battery has played a charge protection, over discharge protection. Where the temperature difference is large, the qualified controller should also have the function of temperature compensation. Other additional functions such as light-controlled switch and time-controlled switch should be optional for the controller.
