Yes. Parallel operation supports up to six compatible units, allowing the total installed inverter capacity to increase as the site's electrical demand grows. Six 12kW units provide a combined nominal output rating of 72kW. This can be useful for an off grid solar system that begins with a limited number of loads but may later add equipment, additional buildings or higher-power machinery. Expansion requires more than connecting additional inverters. Battery discharge capability, AC distribution, communication between units and protection devices must be designed for the intended combined output. If future expansion is likely, planning the battery system and electrical infrastructure from the beginning can make the transition to a larger three-phase installation more practical.
