he Smartsolar MPPT 250/100-tr from Victron Energy (MPN SCC125110210) is part of the latest generation of smart solar controllers from the Dutch premium manufacturer. Ultra-fast power tracking and automatic power point recognition in the event of partial shading are just two of the many highlights of this new device class. This model is also capable of parallel operation with other controllers of the same type. Compared to the Smartsolar 150/….. series, the 250/…. series can handle a maximum PV input voltage of 250V. This is also one of the reasons why the 250 solar controller family has been able to increase efficiency by another 1 per cent to a total of 99%, setting new standards in the industry. This value is currently the best of all solar charge controllers that we know of. Compared to the BlueSolar family, the Bluetooth module is already integrated into the controller of the 250 Smartsolar series, which makes the smart dongle superfluous for this device if you want to analyse and configure the controller via Bluetooth using a smartphone or tablet. Another new feature is the optional LCD display, which can simply be attached to the SmartSolar 150/85-tr as required. If required, the MPPT WireBox-XL Tr from Victron Energy is the ideal addition to your SmartSolar charge controller. It is used to securely connect the cable inputs and connection terminals of the controller.
