Do it Yourself Battery Backup

Tips for the Do It Yourself Installer When planning your back-up power system a sub-panel must be connected through the inverter in the battery back-up system. You will have an alternating current line coming from your main service panel which is connected to the "AC in" on the back-up system. The "AC out" is then sent to the sub-panel only. If you have a power outage the power must be supplied only to the backed up sub-panel, not to the main panel. You will have to relocate specific circuits that you wish to have powered when the grid is down to the new sub-panel. You will need to decide what appliances need to be powered during such and event and have them tied to your sub-panel. You should consult a licensed electrician for this procedure.
