Q:Solar water heater controller power screen is not displayed
Are many kinds of possible, the transformer is broken, the control panel no electricity, the chip is broken, the display is broken
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:How to choose a solar controller
With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions. The controller through the computer chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy rate control , And adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:Solar water heater all intelligent controller how to install
Different manufacturers are not the same, you can call to contact after-sales processing
Q:What is the use of solar controller
Power adjustment function
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:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
In fact, there is a need for greater power loss. If half a day filled with more than 120w, analogy.
Q:What are the solar controller models?
Contact manufacturers, different manufacturers adjustable model is not the same as our company is this model: (light control + time control, time control, testing three models) Beijing reed hi Yuan New Energy Technology Co., Ltd.
Q:How the solar controller wiring,
Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
