What is the maximum number of Spring panels that can be connected in series on the same branch?

Up to 6 DualSun Spring hybrid solar panels can be connected hydraulically.

This number was determined by filling tests with the thermal camera to check for proper venting.

In order to purge the air properly, it is necessary to increase the filling rate to a level of:

  • 200 L/h/portrait panel
  • 250 L/h/panel in landscape

Be careful not to exceed the maximum pressure of 2 bar in the panels when filling.

If these flow rates are not sufficient, please refer to What is the maximum allowable flow rate of DualSun panels?
