Dual AC input and AC output. The MPPTs are independent and can accept up to 12000 watts.
Based on the requirements of our customers we developed this product to serve off-grid projects that require 2 inputs and 2 smart AC outputs with the power flow to be managed by CT sensors (Current Transformers). It sounds complicated but the inverter is user-friendly and the interface with your existing electrical switchboard is very easy to do.
The Ultra-Max is the best-equipped solar inverter on the market, it has all the functions you will ever need for an off-grid system with grid or generator backup.
Having two AC inputs will secure an uninterrupted AC power supply while the super-fast MPPT charger at 150A will top up the batteries efficiently and quickly even when the limited supply from the AC-Sources or Solar.
In addition, Ultra-Max offers an additional AC output that enables the users to customise cut-off voltage, state of charger (SoC) percentage, discharge time and schedule on/off time.
Hybrid Mode with CT (Current Transformer/Sensor)
In case you want to integrate the inverter into the existing electrical installation, without interrupting the connection to the grid, the inverter can function in self-consumption mode (refer to page 50 of the manual).
The single line diagram illustrates the classic operation of the inverter in ESS mode (energy storage system) that works in self-use mode without exporting power back to the grid. In this set up the ac-output of the inverter (off-grid) is not used.
