Description
Overview
The NOVA MAX 3K 2026 combines a 3,000W pure sine wave inverter, an 80A MPPT solar charger and an AC battery charger. This version adds built-in Wi-Fi monitoring and can run up to 9 units in parallel for single-phase, split-phase or three-phase systems.
It runs on a 24V battery bank (AGM, Gel, Flooded or lithium) and accepts up to 3,000W of solar at 90 to 230V DC through its 80A MPPT charger. When grid or generator power is present, it switches over in 10 ms for computers (UPS mode) or 20 ms for appliances, and it restarts automatically when AC power returns.
Choose how it charges (Solar First, Solar and Utility, or Only Solar) and which source powers your loads first (Utility First, Solar First or SBU).
