Do you have any question on our Wellsee solar controller, the following answers is for you to know more about our controller.
1. How many charging mode does the Wellsee controller have?
There are three charging modes. They are PWM and MPPT, MPPT,3phase . 3phase is the most advanced. Wellsee have already developed 3phase charging controller (Also named three-stage charging controller ) with high performance, reliability, efficiency and fast tracking speed.
2. What is a solar charge controller?
Solar Charge Controller (or Regulator) is a device which protects the batteries in a solar electric system from being overcharged or being over-discharged. It is need in virtually all solar power systems that utilize batteries. With the development of technology, controller has more additional functions now, such as load control function, LCD display, hybrid system controllers etc.
3. Can your charge controller be used for Lithium Batteries?
Yes, Our PWM series is a programmable solar charge controller. The charging parameters are adjustable. User can check the battery characteristics and change the parameters accordingly.
4. Why should the controller have temperature compensation function?
As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as temperature falls, charging voltage should be increased to avoid undercharge. In general, to assure optimum service life, use of a temperature compensated charger is recommended.
5. What’s the wiring order of the off-grid system?
1.Battery 2. Load 3.solar panel. Wellsee controller has protection for wrong connections during installation. There won’t be damage to the controllers. However, we still suggest user use the controllers strictly following the instruction manuals
6. Is there any lightning protection for solar charge controller?
Yes. Some level lightning protection is provided in the form of transient voltage protection on both the PV and battery connections in all Solar charge controllers. However, if you live in an area prone to lightning, you should add additional lightning protection devices. Keep in mind that even with additional lightning protection nothing is 100% lightning proof. Damage due lightning is not covered under warranty.
