About this deal
A solar charge controller is at the centre of your solar system. It bridges the gap between your PV array and your battery bank. Make sure you choose the correct controller to prevent any issues down the line.
Regardless, this model can provide bulk charging of up to 80% of capacity. It also provides float charging of the final 20% of capacity and an equalization charge. If there’s no regulation, the batteries can be easily damaged, which will cost you money and time to fix.Malekpour, A.R., Tabatabaei, S., Niknam, T.: Probabilistic approach to multi-objective Volt/Var control of distribution system considering hybrid fuel cell and wind energy sources using improved shuffled frog leaping algorithm.

The Victron SmartController offers built-in Bluetooth connectivity to any Bluetooth-enabled device, such as a smartphone. With an internet connection, users can use the Victron Remote Management Portal app from anywhere, and it’s free! Usually, we will declare a reasonable minimum value to save your customs tax. But due to the different policies in different countries, the customs may ask you to pay the tax. Zitzler, E.: Evolutionary algorithms for multiobjective optimization: methods and applications.
