SmartSolar MPPT 250/60-Tr

MPPT (Maximum Power Point Tracking) technology optimizes energy harvesting from solar panels. The SmartSolar MPPT 250/60-Tr controller uses ultra-fast MPPT technology that improves energy recovery by up to 30% compared to PWM controllers and up to 10% compared to slower MPPT controllers, especially under cloudy skies or during changes in light intensity.

The SmartSolar MPPT 250/60-Tr controller can manage the following nominal PV power ratings:

860 W for 12 V systems
1720 W for 24 V systems
2580 W for 36 V systems
3440 W for 48 V systems
If a higher PV power is connected, the controller will limit the input power.

The SmartSolar MPPT 250/60-Tr charge controller supports 12 V, 24 V and 48 V battery voltages with automatic selection. For 36 V systems, software is required for selection.

No, the SmartSolar MPPT 250/60-Tr controller does not require a cooling fan. It delivers maximum conversion efficiency exceeding 99 %, ensuring silent operation.

In case of partial shading, the SmartSolar MPPT 250/60-Tr’s innovative algorithm ensures maximum energy harvesting by always locking onto the optimal maximum power point (MPP), preventing it from getting stuck on a local MPP that would not be the best.

The maximum conversion efficiency of the SmartSolar MPPT 250/60-Tr controller exceeds 99%.

Yes, the SmartSolar MPPT 250/60-Tr controller features a fully discharged battery recovery function. It will initiate charging even if the battery has been discharged to zero volts and will reconnect to a fully discharged Li-ion battery with integrated disconnection function.

The controller integrates extended electronic protections, including:

Overheat protection and power derating in case of high temperature.Protection against PV short circuits.Protection against PV polarity reversal.Protection against PV reverse current.

The SmartSolar MPPT 250/60-Tr controller can operate within a temperature range of -30 to +60 °C. Full nominal power is maintained up to 40 °C.

The charge algorithm is fully programmable. You can configure it via the VictronConnect app (built-in Bluetooth Smart), via the VE.Direct port, or by using one of the eight pre-programmed algorithms selectable with a rotary switch.

For the Tr model (screw type), the PV terminals and battery terminals accept cables with a cross-section up to 35 mm² / AWG2.

Yes, an optional SmartSolar plug-in LCD display is available. Simply remove the rubber gasket protecting the front port of the controller and plug in the display.

The SmartSolar MPPT 250/60-Tr controller firmware can be updated wirelessly via the VictronConnect app using the built-in Bluetooth Smart.

The SmartSolar MPPT 250/60-Tr controller has an IP43 protection rating for the electronic components and IP22 for the connection area. It is designed for indoor use in non-climate-controlled conditions.

Yes, up to 10 SmartSolar MPPT units can be synchronized for parallel charging via Bluetooth Smart.

Yes, the controller is compatible with external battery voltage and temperature sensors via Bluetooth. You can use a Smart Battery Sense, a BMV-712 Smart Battery Monitor, or a SmartShunt to send this data (and current, for the BMV-712 or SmartShunt) to one or more SmartSolar controllers.

Yes, the SmartSolar MPPT 250/60-Tr controller has a VE.Direct port that allows a wired connection to devices such as a Color Control GX, other GX products, or a PC for data communication.

Yes, the controller can charge lithium-ion batteries. It can even reconnect to a fully discharged Li-ion battery with an integrated disconnect function. The charging algorithm is also fully programmable to adapt to specific lithium battery requirements.

The maximum absolute open-circuit voltage of the PV panels that the controller can accept is 250 V under the coldest conditions. The maximum start-up and operating voltage is 245 V.

Yes, the SmartSolar MPPT 250/60-Tr controller is equipped with a programmable relay. This relay can be configured, for example via a smartphone, to trigger on an alarm or other specific events. Its AC rating is 240 VAC / 4 A and its DC rating is 4 A up to 35 VDC, and 1 A up to 60 VDC.
