4. operations SUNCONTROL2, charges up to two batteries: one service battery (B1) and one starter battery (B2), with priority charging to the service battery. SUNCONTROL2 will start charging the batteries if the following conditions are satisfi ed: 1. The connected Solar Panels deliver a voltage 1V higher than the voltage of the batteries to be recharged. -

Is it possible to connect one 200W solar panel only, on a single SUNCONTROL2 connection? It’s possible to connect just one bigger solar panel (200W), for example on SUNCONTROL2 Pin N°5, but you must connect Pin N°5 and Pin N°6. Use, at least, a 6 mm cross-size cable. -

Questions and answers
Hi I have no led light showing
A possible reason for no LED light showing on the NDS SUNCONTROL2 could be a faulty LED on the control panel. Users have reported similar issues where only one LED (B1 or B2) is illuminated, and the other is unlit despite both batteries reading 100%. This suggests the LED itself may be defective, not the battery or charging system.
