[FAQS about 60v inverter can convert to 72v]
No, a 72-volt inverter should not be connected to a 60-volt system. The 72-volt batteries are typically composed of six batteries connected in series, while 60-volt batteries consist of five batteries connected in series. This fundamental difference in voltage configuration means that a 72-volt inverter is not designed to operate with a 60-volt system1. Additionally, using a 60V controller with a 72V inverter may lead to compatibility issues and is generally not advisable2. [pdf]
