Best Renewable Energy Controllers Buying Guide
Before choosing the best renewable energy controllers you should consider the following options:
1. Modular or integrated: A key decision point in choosing a solar controller is whether to go for a modular or an integrated system. Modular controllers are usually cheaper and easier to install, but they are a bit less efficient.
Integrated controllers are more expensive, but they offer greater efficiency and more seamless integration of the solar energy system into the overall electricity grid.
2. Maximum power point tracking (MPPT): MPPT technology helps maximize the power output of the solar PV modules in order to harvest more energy from the solar PV array. The advantage of this technology is that it increases the overall efficiency of the solar PV system.
3. Maximum capacity: The maximum capacity of a solar controller is expressed in kW and must be selected according to the size of the solar PV array. The power rating of the controller must be greater than the total maximum power of all the modules in the solar PV array.
Also, note that the maximum capacity should be greater than the maximum power consumption of the entire electrical appliances in the home or office connected to the solar PV system.
4. Maximum voltage: The solar controller must be selected according to the voltage of the solar PV array. In general, the nominal voltage of a solar PV array is either 12 or 24 volts.
However, in some cases, 36-volt solar PV arrays are also available. The most common solar controllers operate with a maximum voltage of 1000 volts, which is suitable for most residential solar PV systems.
5. Maximum current: The current rating of the solar controller must be adequate to support the maximum current of the solar PV array. The current rating of the solar controller is expressed in Amps, and the selection must be based on the maximum current of the solar PV array.
6. Maximum power tracking and battery charging: The solar controller must be selected according to the type of application. In case the solar PV system is going to be connected to the electricity grid, the controller must have sufficient features to support and smooth out the output of the solar PV array.
