Automatic Transfer Switch for Offgrid Solar

​(I make a commission for purchases made through the links below)

If you have an off-grid solar power system AND grid power, use this switch to power your devices until the solar battery is low, then it will switch to grid power. This is a great switch to use if you have a stationary RV and wish to use both solar power and grid power. You can also program the cut-off voltage (the battery voltage when it switches to grid power), so that your batteries last a long time. You can also program the reconnect voltage as well. 

Very easy to setup! Run some extension cords to the terminals and plug it into your system. It will turn on when you connect your solar battery to the terminals. It can work with 12/24/48 volt solar power systems

Manual Transfer Switch for Solar Systems

This switch is technically automatic, but it will only kick back to grid power when you turn the inverter off. So its only semi-automatic, unless you can manually set the disconnect threshold on your inverter, and the reconnect voltage. If you can, you can use this. If you want to save time, use the one I mentioned at the top of this page.
