Off-grid home power kit: reliable, powerful, and scalable

This BESS kit combines a pure sine wave hybrid inverter 5 kW (48 V DC → 220 V AC) and a pack of 4 lithium LiFePO4 batteries 12 V 280 Ah Bluetooth, to form a complete storage and energy management solution. Perfect for an isolated house, a cabin, a tiny house, a workshop, or as a home backup system.

Key features

• Power 5,000 W (pure sine wave) – up to 10,000 W peak: compatible with many devices (refrigerator, coffee maker, air conditioning, tools, etc.).
• High-efficiency MPPT 80A solar controller (manufacturer data), with wide MPPT range 120–450 VDC.
• Total nominal storage: 14.3 kWh (4 × 3584 Wh) – usable energy depending on settings and depth of discharge.
• Grade A LiFePO4 Batteries + integrated BMS: safety and longevity (manufacturer data: > 6000 cycles at 100% DOD / lifespan > 15 years, depending on conditions).
• Bluetooth 5.1: real-time monitoring (voltage, SOC, current, temperature) via the ECO-WORTHY app.
• Low temperature protection: charging protected below -7°C (resumes at 0°C) and discharge cut-off below -20°C to preserve cells.
• UPS function: automatic switch to batteries in case of power outage for continuous supply.
• Flexible management: charge priority (solar/grid) and ability to schedule charge/discharge periods according to rates (off-peak hours, etc.).

Recommended uses

• Off-grid home: lighting, internet, appliances, TV, small tools, etc.
• Domestic backup (essential circuits): fridge/freezer, box, lighting, pump, etc.
• Workshop / farm: powering devices and tools within the inverter's power limit.

Kit contents

Important advice (safety & sizing)

• The pack is generally wired in series (4 × 12V → ~48/51.2 V) to be compatible with the inverter.
• Use identical cables, a DC protection (fuse/circuit breaker) and an appropriate isolator.
• For solar: check that the open-circuit voltage (Voc) in cold of the PV array remains < 450 VDC.
• Installation recommended by a qualified professional (standards, protections, grounding, cable sections).
