Sofar Solar Tri 8 kW Hybrid Inverter – HYD8KTL-3PH

Sofar Solar HYD8KTL-3PH – 8 kW three-phase hybrid inverter

The Sofar HYD8KTL-3PH: 8 kW three-phase, 16 kVA peak power, compatible with all 48V to 800V batteries

The Sofar Solar HYD8KTL-3PH is the 8,000 W three-phase hybrid inverter in the HYD range. It shares the same robust design as the HYD 6KTL-3PH — same housing (571×515×264 mm), same universal battery compatibility from 48V to 800V, same parallel capacity of up to 10 units — but with a rated power of 8 kW, a PV capacity of 12,000 Wp and an exceptional EPS peak power of 16,000 VA for 60 seconds. It is designed for large homes, farms and SMEs connected to a 400V three-phase supply requiring maximum backup power.

16 kVA peak EPS for 60 seconds: the most generous backup power in the range

This is the HYD8KTL-3PH’s key advantage over the 6KTL: in UPS mode (battery backup power supply), it can deliver 16,000 VA for 60 seconds — twice its rated power. This reserve allows even the most demanding equipment to be started without difficulty:

• Three-phase heat pumps and industrial compressors (high inrush current on start-up)
• Three-phase machine tools in workshops or on farms
• Multiple simultaneous loads during a mains power cut
• Three-phase electric vehicle chargers in backup mode
• Three-phase agricultural ventilation and irrigation systems

Switchover to UPS mode takes less than 10 ms — imperceptible to almost all electronic and industrial equipment.

Universal battery compatibility: 48V to 800V

The battery voltage range of 180 to 800V allows connection to virtually any lithium-ion or lead-acid battery on the market:

Nominal charge/discharge power: 8,000 W, max current 25A (peak 40A/60s). Auto-adaptation to BMS via CAN/RS485.

Can be connected in parallel with up to 10 inverters: maximum scalability

Up to 10 HYD8KTL-3PH units in parallel on the EPS and AC ports, enabling the creation of a three-phase microgrid of up to 80 kW. Ideal for:

• Large agricultural operations with high three-phase consumption (pumps, greenhouses, ventilation)
• SMEs and industrial workshops requiring total power continuity
• Off-grid microgrids
• Projects requiring a gradual power increase in 8 kW increments

What this inverter actually does

• It converts solar energy into 230/400V AC three-phase electricity with a maximum efficiency of 98% and MPPT efficiency of 99.9%
• It stores surplus energy in the connected battery for use in the evening or during a grid outage
• It automatically switches to EPS mode in the event of a grid outage in <10 ms, with a peak power of 16 kVA for 60 seconds
• It feeds surplus energy back into the three-phase grid if your contract allows it

With 16 to 24 panels (8 to 12 kWp) and a 10 to 30 kWh battery, a large property or farm can achieve 70 to 85% self-consumption, representing an estimated saving of between €1,200 and €2,500 per year.

Advanced features

• Integrated multi-mode EMS: self-consumption, Time of Use (configurable time slots and days), battery backup, full feed-in, off-grid
• Parallel operation: up to 10 inverters on EPS and AC ports
• Compatible with AMASS Store GTX 3000-H (Sofar high voltage)
• Warranty extendable up to 20 years (see pricing in the attachments)

Monitoring: SolarMan Smart

Wi-Fi, Bluetooth, LAN (Ethernet) and RS485 integrated as standard. The SolarMan Smart app (iOS / Android) allows you to view production, consumption and battery status in real time, configure modes and time slots, and control the system remotely.

Installation

Installation must be carried out by a qualified electrician. Key points:

• Three-phase 230/400V mains supply required
• 4-pole main circuit breaker (minimum 20A per phase)
• Battery cabling rated for 25A nominal / 40A peak
• Operates without a battery immediately upon installation
• A CHINT DTSU666 three-phase meter is recommended for managing self-consumption — see the DTSU666 meter
