High-performance hybrid solar inverter for off-grid homes, backup power and energy storage.

Compact solar inverter that does everything in one unit. It provides smooth power during outages thanks to its fast switching and strong surge support. It is perfect for off-grid homes, backup systems and battery storage setups that need constant, stable power.

Compatibility

This solar inverter is compatible with a range of lead-acid and lithium batteries, as well as many generator brands, making it a versatile choice for various energy needs. Its ability to work without a battery offers added flexibility for users seeking different operational configurations.

Key Functions

  • All-in-one power solution:
    • Combines a pure sine wave inverter, dual MPPT solar controller, and smart battery charger in a single compact unit for streamlined installation and maximum performance.
  • High surge capacity & ultra-fast transfer:
    • Handles demanding loads with ease. Lightning-fast 4 ms transfer ensures uninterrupted power to essential appliances during outages.
  • Scalable & flexible:
    • Can be paralleled: up to 3 units in single-phase or 9 units in three-phase setups, supporting maximum outputs from 27 kVA to 72 kVA for high-demand installations.
  • Dual MPPT technology:
    • Supports multiple solar arrays with a max PV open-circuit voltage of 250V, optimizing energy harvesting for 5 kW, 6 kW, and 8 kW systems.
  • ESS & grid-tie ready:
    • Integrates with E4 LCD Monitor and IC-METER for energy storage management, self-consumption optimisation, peak shaving, and optional grid feed-in for utility credits.
  • AC transfer switch:
    • Rated up to 32A, passing up to 7.36 kW from the AC input when in bypass mode.

Intelligent Features

  • Automatic Generator Start (AGS):
    • Activates the generator only when needed, optimising energy use and efficiency.
  • Remote monitoring & control:
    • Monitor and adjust system performance anytime via the Nova Web or mobile app with the TBB-KIN2 Kinergy-II Wi-Fi module.
  • Ultra-fast battery transfer:
    • 4 ms switch ensures uninterrupted power during outages. ECO Mode extends backup time while keeping self-consumption extremely low.
  • High efficiency:
    • Up to 95% inverter efficiency and 98% MPPT efficiency maximise energy capture and utilisation.
  • Hassle-free operation:
    • All-in-one design simplifies installation and maintenance, with automatic restart when PV or AC power is restored.

*Please note: The option to work without a battery is only for single-use application with stable AC bypass supply, PV energy as a supplement for AC bypass.*
