FAQ – Sofar Solar Tri 20 kW Hybrid Inverter – HYD20KTL-3PH

1. What is the Sofar Solar HYD20KTL-3PH hybrid inverter and what is it designed for?+
The Sofar Solar HYD20KTL-3PH is a 20,000 VA / 20,000 W transformerless three-phase hybrid inverter — the most powerful model in the HYD-TL-3PH range. It converts solar energy into 230/400 V three-phase AC power, manages high-voltage battery storage, and provides an unbalanced three-phase UPS backup power supply in the event of a grid outage. With a maximum efficiency of 98.2% and a European efficiency rating of 97.7%, it is designed for large, high-consumption residential installations, SMEs, agricultural operations and microgrid projects requiring maximum power and scalability.
2. What is the difference between the HYD20KTL-3PH and the HYD15KTL-3PH?+
Both models share the same architecture (2 MPPT trackers, 2 battery inputs, parallel connection of up to 10 units, unbalanced three-phase power supply, identical dimensions and weight: 571.4 × 515 × 264.1 mm / 37 kg) and the same certifications. The key differences relate to power output: the HYD20KTL-3PH delivers 20,000 W (vs 15,000 W), with a nominal output current of 29 A (vs 21.7 A) and a full-load battery voltage range of 400–800 V (vs 300–800 V for the 15K). The nominal battery charge/discharge power is also higher: 20,000 W distributed across 2 inputs (10,000 W each vs 7,500 W). The HYD20KTL-3PH is therefore the preferred choice whenever three-phase consumption exceeds 15 kW or the PV installation requires a higher conversion capacity.
3. Which batteries are compatible with the Sofar HYD20KTL-3PH and what storage capacity is possible?+
The HYD20KTL-3PH supports high-voltage lithium-ion and lead-acid batteries, with a voltage range of 180 to 800 V (nominal voltage 600 V, full-charge range 400–800 V). It features 2 independent battery inputs communicating via CAN or RS485, allowing for scalable capacity in 2.5 kWh increments. It is compatible with Sofar Solar BTS 5K batteries (in configuration with BDU, from 5.12 to 40.96 kWh), Pylontech (US2000C, US3000C, US5000, H48050, UP2500) and a wide range of high-voltage batteries. The maximum charge/discharge current is 50 A (25 A per input), with a peak of 70 A (35 A per input) for 60 seconds.
4. How does the HYD20KTL-3PH’s EPS emergency output function in the event of a mains power cut?+
The HYD20KTL-3PH features a dedicated three-phase EPS (Emergency Power Supply) port that switches over automatically in under 10 ms during a mains power cut — a delay imperceptible to your devices. A key feature is its ability to power unbalanced three-phase loads (different loads on each phase), which reflects the reality of a domestic or commercial setting. In EPS mode, the nominal output power is 20,000 W with a maximum current of 32 A, and a peak power of 22,000 VA for 60 seconds for starting high-inertia loads (motors, compressors, air conditioning). Connected and sufficiently charged batteries are required.
5. Can several HYD20KTL-3PH inverters be connected in parallel to increase power?+
Yes. The HYD20KTL-3PH supports parallel operation of up to 10 units, on both the mains AC port and the EPS port. This allows a total power output of 200 kW to be achieved — in grid-connected or stand-alone mode — making it one of the most scalable solutions on the market for industrial microgrids, large-scale agricultural sites or community projects. This scalability allows you to start with one or two units and gradually expand capacity as needs evolve, without changing the architecture.
6. What operating modes and control options does the HYD20KTL-3PH offer?+
The inverter features an integrated EMS (Energy Management System) that can be configured via the LCD screen or the app: automatic self-consumption, time-of-use scheduling (off-peak/peak hours), rules by day of the week, grid injection and off-grid mode. The built-in LCD screen, combined with Bluetooth connectivity and the app, allows for configuration without a PC. A Wi-Fi dongle is supplied as standard to access the Sofar monitoring portal; Ethernet and 4G options are available. Communication is via RS485 and CAN 2.0. Standby power consumption is less than 15 W, minimising the energy impact during periods of inactivity.
7. What certifications and built-in protections does the Sofar HYD20KTL-3PH have?+
The HYD20KTL-3PH is certified to the main European grid connection standards: VDE V 0124-100, V0126-1-1 and VDE-AR-N 4105 (Germany), IEC 0-16 / IEC 0-21 (Italy), EN 50549, G98 / G99 (United Kingdom), UTE C15-712-1 (France), as well as the safety standards IEC 62109-1, IEC 62109-2 and IEC 62040-1. EMC compliance is ensured in accordance with EN 61000-6-1 and EN 61000-6-3. The inverter incorporates comprehensive protection features: DC switch, Type II SPD on the PV side and Type III SPD on the AC side, islanding protection, residual current detection, insulation resistance detection, and battery reverse connection protection.
8. What are the dimensions, weight and installation requirements of the Sofar HYD20KTL-3PH?+
