Hybrid three-phase inverter SOFAR ESI-6.5K-T1 PowerAll, 6.5kW, 3MPPT, DC disconnect, IP65 901030200049-0

Three-phase hybrid inverter 6.5 kW with three MPPT and built-in DC disconnect

This device integrates photovoltaics, battery, and grid power into a single system. It operates both grid-tied and off-grid — when grid power fails, it automatically switches to battery supply. No additional relays or switching units are required — everything is fully integrated.

The built-in DC disconnect allows safe isolation of photovoltaic panels without the need for an external disconnect device. This simplifies installation and reduces the risk of errors during servicing — especially critical when working on roofs or in hard-to-reach locations.

The system supports three independent MPPT channels, each with a maximum input current of 20 A. This enables connection of PV panels with different parameters — for example, on different roof orientations — without performance losses. Maximum PV input of 13 kWp with a 6.5 kW output is standard oversizing, which increases energy production under real-world conditions such as cloud cover or low temperatures.

Batteries are connected via a single DC input with a voltage range of 350–435 V — compatible with BTS 5K batteries. Maximum charging power is 10 kW, discharging power is 6.5 kW. Charging current up to 25 A, discharging current up to 19.5 A — fast enough to respond to sudden changes in household or commercial load demand.

You can manually set battery charging and discharging times — ideal for variable tariffs (e.g., G12). Charge with cheap nighttime electricity and consume it during peak hours — reducing bills and shortening payback period.

RS485 communication enables monitoring via energy management systems. Optional WiFi/4G/LAN connectivity is available but not standard. The LCD display shows real-time operating data: output power, battery state of charge, PV generation, and grid parameters.

The unit is wall-mounted. Passive cooling — no fan — ensures quiet operation and higher reliability. IP66 rating allows outdoor installation without an additional enclosure — even in rain, dust, or high humidity.

Operating temperature range: -30°C to +60°C (power derates above +45°C), enabling reliable performance in diverse climates. Weight: 30 kg; dimensions: 708×440×170 mm — standard for this power class, easy to transport and install by a single technician.
