How to Connect Batteries in Parallel with Power Inverter or UPS [Wiring Diagrams]



Connect multiple batteries in parallel with your power inverter or UPS to increase its backup. If you own a single battery inverter, you can connect more batteries in parallel as overall voltage of pack will remain the same while capacity multiplies. Make sure that your power inverter could afford charging several parallel connecting batteries at a time. If charger is slow, you should avoid connecting larger batteries. Check the inverter or UPS specifications to find out if charging current could be increased as that will help boost battery charging and shorten time to fully charge batteries.

As a reference, we have explained how to connect 2, 4, 6, 8 or 10 batteries in parallel to power backup devices. You may connect any number of batteries in parallel keeping few things in mind which are discussed under “Detailed Discussion” heading below. Make sure to read it to get more information about parallel battery pack and safety information.

Eight Batteries in Parallel with Power Inverter or UPS

Ten Batteries in Parallel with Power Inverter or UPS


Detailed Discussion:
Every power inverter or UPS can charge certain capacity of batteries. Your inverter may start giving error if excessive capacity batteries are connected. Even several small batteries connected in parallel can result in excessive capacity and may cause problems.

Never connect multiple batteries in series to inverter that could cause over voltage. For example, if your inverter accepts 12V battery, do not connect 24V series pack to it. But you may connect 6 2V batteries in series to it to multiply voltage to 12V.

Avoid reversing battery polarity. That may damage inverter or UPS if it does not have reverse polarity protection. Also while connecting cables to batteries, make sure that short circuit does not happen. High capacity batteries can cause huge sparks and ignite fire. So be careful while wiring such batteries together.
