Disconnecting Solar Panels Safely

The instructions for my solar panel say.

Disconnecting solar panels safely.

Connect the battery to controller then the controller to solar panel that being the case to disconnect would be in reverse order. Typically the company from whom you originally purchased the panels should perform the work. Some larger systems use a solar power disconnect switch for added safety in case one of the solar panels gets exposed to light during maintenance. The solar safety shutoff is capable of simultaneously isolating solar panels stopping the combining of panel voltages and limiting the system voltage to the safety of extra low voltage outlined in green on the diagram below.

For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode. I thought that without the battery connected the solar panel would fry the controller. The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery. Step 4 cover the ends of each wire with electrical tape a plastic bag or a rubber terminal cover to prevent physical contact should the wires become live.

Pvstop is the only safe way to deactivate panels at the source the solar panels themselves. Solar panels cannot be turned off when exposed to light. Any solar installer or solar company can remove panels for you in order to complete the work safely. Furthermore installers and solar companies will carry insurance that allows them to cover any damage that occurs in the event of an accident.
