Description

The SolaX X3-HYB-15.0-P is the most powerful model of the G4 PRO series: 15 kW rated power (up to 16.5 kVA), array up to 30 kWp, EPS 15 kVA with a 30 kVA peak, two battery ports and three MPPTs. It is meant for a large house, a farm, a workshop or a business that needs 15 kW of power, a large battery (two towers, up to 50 A) and backup with a generator. Compared with the standard 15 kW G4: here the output has a 110 % margin (16.5 kVA versus 15 kVA), the EPS peak is 30 kVA versus 22.5 kVA, and the housing is IP66.

Battery without compromise

BAT1 and BAT2, 120–800 V (about 400 V recommended), 30 A to one port, 2 × 25 A to both, 50 A to one tower with the 2-in-1 cable (sold separately). The full 15 kW from one tower through 30 A needs 10 modules (512 V); with the 2-in-1 cable at 50 A, 6 modules are enough (307 V × 50 A ≈ 15.4 kW) – the battery's own current limit is then checked too (S36 – up to 50 A). Two towers of 6 modules of T-BAT SYS-HV-S36 (22.1 kWh each) or TSYS-HS51 (30.7 kWh) at 25 A each give 15.4 kW together and 44–61 kWh of capacity. Only lithium batteries connect.

Array up to 30 kWp

Three MPPTs at 20 A (25 A short-circuit), window 110–950 V, start-up 120 V, full power 330–800 V, maximum PV voltage 1,000 V. Rated output current 21.8 A, maximum 25.0 A per phase. Maximum efficiency 98.0 %, European 97.7 %. In parallel up to 10 inverters – for 150 kW systems.

Backup and generator

EPS 15 kVA, switchover faster than 10 ms, 10 s peak 30 kVA – compressors, pumps and workshop motors start. Generator and microgrid modes for long outages. For switching the whole site – the X3-EPS Box (up to 63 A per phase).

Installation and communication

Housing 560 × 503 × 210 mm, 38 kg, IP66, fan up to 45 dB – a plant room, a garage or an outdoor wall under a canopy. Operating temperature −35 °C to +60 °C (derating above 45 °C). Type II SPD on the DC and AC side, insulation and residual-current monitoring, optional AFCI. Communication: RS485, CAN, DRM, DI/DO, heat-pump and DataHub terminals, LCD display, DTSU666 meter or CT; SolaX Cloud via the Pocket Wi-Fi + LAN dongle.
