Key Features

Benefits

• Maintains charging performance in changing light conditions with ultra-fast MPPT.
• Reduces mismatch losses under partial shading through advanced MPP detection.
• Supports system integration through VE.Can, VE.Direct and Bluetooth.
• Can initiate charging from a fully discharged battery.
• Allows synchronised parallel operation with multiple controllers.

Technical Summary

Victron SmartSolar MPPT charge controller, model 250/85. Rated charge current 85 A. Battery voltage 12/24/48 V auto select, with 36 V manual setting. Maximum PV open-circuit voltage 250 V absolute maximum, 245 V start-up and operating maximum. Nominal PV power: 1200 W at 12 V, 2400 W at 24 V, 3600 W at 36 V and 4900 W at 48 V. Maximum PV short-circuit current 70 A. Protection category IP43 for electronic components and IP22 at the connection area. Operating temperature -30 to +60 °C.

Installation Notes

MC4 model with three pairs of MC4 PV connectors; maximum current per MC4 connector is 30 A. PV voltage must exceed Vbat + 5 V to start, then remain above Vbat + 1 V for operation. Indoor, unconditioned installation with IP43 electronics and IP22 connection area. Optional SmartSolar pluggable LCD display can be fitted by removing the front rubber seal and plugging in the display.

Efficiency

Maximum efficiency exceeds 99%. Ultra-fast MPPT is stated to improve energy harvest versus PWM controllers and slower MPPT controllers. Self-consumption is less than 35 mA at 12 V and 20 mA at 48 V.
