SunWare Cell-Protector
Applies only to SunWare solar panels with three wire cable!

The purpose of the cell-protector is to prevent overheating of the solar cells when the solar module is partial shaded (Hotspot), this is achieved by the diodes on the cirquit board. ( By standard aluminium framed glass modules these diodes are located in the junction box on the backside of the modules.) To replace easily the diodes in the case of damage, SunWare integrates the two diodes mostly in the external cell-protector and not in the junction box. At all 24V SunWare solar panels the diodes are integrated inside the laminate.
Before using your solar module, you have to connect the enclosed cell-protector!
The cell-protector has to be mounted / operated in a dry place, it must not become wet or moist with dew. The cable of each single SunWare solar module has to be conntected to one single cell-protector. Only behind the cell-protector, modules could be connected in series or parallel.
The cell-protector is also to reorder in our Online-Shop.
Connecting the cell-protector
Connection possibilities
Bypass +
Reverse current protection
Left: two cables to charge controller,
terminals "+_D", "-".
With this hookup, the cells are protected with 2 bypass diodes against the hot spot effect and the additional blocking diode protects against reverse current back into the module.
By damage to a module or cable by several modules in parallel operation an influence can be prevented on the other modules with the use of the blocking diode.
