Felicity Solar kit 14.14kWp with 16kWh storage – IVGM12KLP3G1 12kW three-phase hybrid inverterThree-phase kit: 28 Trina 505W modules, 12kW Felicity hybrid inverter, 16kWh battery and protection boxes

Overview

For a modern house on a three-phase supply, with heat pump, induction hob and an electric car charged at night. The Felicity IVGM12KLP3G1 12kW inverter accepts 18kW of PV and up to 350A of battery current, more than this storage needs: the single-piece FLA48314-EU battery works at 160A continuous, 8kW, so its 16kWh charge or discharge in two hours. Twenty-eight Trina 505W modules give 14.14kWp in two strings of fourteen at 532V, well inside the 800V limit. The three-phase AC box with CEI 0-21 interface protection and the two-string DC box are included.

• Inverter and battery from the same maker, native CAN
• 48V kits: 8kW single-phase, 12, 15 and 20kW three-phase
• High-voltage kits: 30kW with 30.72kWh, 50kW with 61.44kWh
• PV versions with Trina Solar Vertex S+ 505W modules and protection boxes
• Switch-over to backup in under 10ms
• 10-year warranty on inverter and batteries

What's in the kit

• 28 × Trina Solar Vertex S+ 505W PV modules
• 1 × Felicity Solar IVGM12KLP3G1 Hybrid inverter
• 1 × Felicity Solar FLA48314-EU Battery
• 1 × AC 15kW 25A AC protection box with CEI 0-21 interface protection
• 1 × DC 2 MPPT 900V DC string box

How the kits are built

The combinations follow Felicity's official datasheets: each inverter is paired with batteries whose current and voltage fit its battery input, and the 50kW kit with 61.44kWh is the system Felicity itself publishes. The PV versions add Trina Solar Vertex S+ 505W modules in strings sized for the inverter, plus the AC and DC protection boxes.

Low or high voltage

The 48V kits use floor-standing Felicity batteries that can be paralleled up to fifteen units, so storage grows one battery at a time. Above twenty kilowatts the high-voltage kits run at 614.4V: the same power flows with a quarter of the current, with heated IP65 modules in the 30kW kit and a rack cabinet in the 50kW kit.
