Felicity Solar kit 18.18kWp with 32kWh storage – IVGM15KLP3G1 15kW three-phase hybrid inverterThree-phase kit: 36 Trina 505W modules, 15kW Felicity hybrid inverter, two 16kWh batteries and protection boxes

Overview

Thirty-two kilowatt-hours behind a 15kW inverter suit a large house or a small business that also works in the evening: two floor-standing FLA48314-EU batteries of 16kWh in parallel on the same 48V bus. Thirty-six Trina 505W modules give 18.18kWp in two strings of eighteen at 684V, inside the inverter's 800V limit; the IVGM15KLP3G1 accepts up to 22.5kW, so the array can still grow. The two batteries deliver 320A continuous, 16kW, more than the inverter's rating, and time-of-use programming charges in cheap hours. The AC box with CEI 0-21 interface protection and the 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

• 36 × Trina Solar Vertex S+ 505W PV modules
• 1 × Felicity Solar IVGM15KLP3G1 Hybrid inverter
• 2 × 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.
