Q1. What is the voltage?
A1. Our 45/60A solar charge controller is 12/24/36/48V auto work.
Q2. What is the difference between MPPT&PWM?
A2. MPPT has higher efficiency, it can track the max power point and won't waste energy.
Q3. What is the efficiency of the MPPT controller?
A3. MPPT>99%, peak conversion efficiency>98%.
Q4. What is the waranty of product?
A4. 12 months.
- Q:Solar water heater controller power screen is not displayed
- Check the circuit, if the circuit is good, then you have to get the seller to see, because you know where is bad, you no tool material, can not change.
- Q:Solar controller 10a, a represents what
- 10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
- Q:Solar controller can not charge what is the reason
- Are charged control point voltage: direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the charge state. Why are they designed? That is, when the direct charge is completed, there may be individual batteries "backward" (terminal voltage is relatively low), in order to pull these individual molecules back, so that all the battery side voltage is uniform, so it is necessary to high voltage with moderate Of the current and then charge a small meeting, we can see the so-called charge, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, it is not meaningful. Therefore, the street lamp controller is generally not full charge, only two stages
- Q:Solar water heater all intelligent controller how to install
- This is the most widely used solar water heater installation program, the solar energy operation by the solar controller 8 control, when the solar water heater tank water level below the minimum water level, the controller to open the solenoid valve 1, making the water tank, When the water level rises to the user set the highest water level, the controller closes the solenoid valve 1, the water stops. The user can specify the water time, when the specified time to, as long as the water level does not exceed the maximum water level, the controller will open the solenoid valve 1 water until the water level to the highest water level. The controller can also manually force the water: When the manual water key is pressed, the controller opens the solenoid valve until the water level reaches the highest water level.
- Q:What is the meaning of the 30A solar controller?
- Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
- Q:What brand of solar controller is good
- The State Administration of Quality Supervision, Inspection and Quarantine announced the Chinese brand-name products, the entire solar water heater industry is currently only selected eight companies, as follows: force Norit Shandong force Norit New Energy Co., Ltd. billion to Shandong billion solar energy Co., Ltd. Sunrise Oriental sun rain Lianyungang City sun rain water heater Manufacturing Co., Ltd. Huayang Jiangsu Province, Yang Yang Solar Co., Ltd. Huang Ming Shandong Huang Ming Solar Group Co., Ltd. Sang music digital Shandong Sang Le Solar Co., Ltd. Tsinghua sunshine Beijing Tsinghua sunshine solar equipment limited liability company Brilliant Jiangsu Huaiyin brilliant solar energy limited company
- Q:Solar controller does not heat how to heat
- Solar controller with live heating, with no electric heating, and now your controller without electric heating, can only replace a charged heating. "Solar public welfare network" free consultation
- Q:Solar controller red light flashing
- Solar controller flashing red light according to the different brands of the representative of the meaning of the controller are not the same, but in general terms, the red light flashing a saying that the battery is charging the battery is expressed as a red light flashing, green , The yellow light does not shine; another kind is the battery high pressure state or battery low voltage state that is red light flashing, green light does not light, hope to help you
- Q:How to debug a solar street light controller
- Press the button for more than 3s digital tube began to flash, the system into the adjustment mode, release the button, each press a button, digital tube digital will change a number until the digital display of the number of users from the table selected mode corresponding The number of so far, such as digital tube to stop flashing or press the button more than 3s to complete the set.
- Q:Choose a solar controller which need to have a few conditions
- The controller should have battery overvoltage protection, battery undervoltage protection, load short circuit protection, temperature compensation and other functions, select the controller to choose the quality of the guarantee. Big manufacturers big brand
