Automatically assigns communication addresses to slave modules, making the parallel connection process straightforward and efficient. Capable of short-time high-current charge and discharge with an impressive 95% depth of discharge (DoD) and a lifespan of up to 8,000 cycles. Each battery pack includes an advanced Battery Management System (BMS) for effective monitoring and management of modules. Warranty: 7 years. Sunsynk ECCO 5.0kW 48V off-grid hybrid inverter/charger: This innovative unit combines the functions of a 5000W pure sine wave inverter, two 50A MPPT solar charge controllers, and a 40A mains/generator battery charger in a single device. The inverter is compatible with input up to 6500W solar panels, mains power, a generator, or a battery, with the flexibility to use one or multiple input sources simultaneously. The ECCO provides a dry‑contact GEN signal (G‑S / GV) that closes when battery SOC/voltage drops below a set threshold; this signal can start an auto‑start generator a single‑phase automatic transfer switch (ATS) rated for 45 A continuous (around 6–7.5 kVA) to safely switch between grid and generator, plus a way to interface the inverter’s GEN dry‑contact signal. With hybrid capabilities, advanced communication functions, and highly customisable settings, the inverter delivers 5,000W of continuous AC power and up to 5,500W during peak demand to power appliances like pumps, vacuum cleaners, or power tools. The built-in MPPT solar charge controllers maximises solar panel efficiency and offers comprehensive safety features, including overcharge, overheating, and reverse current protection. Its LCD screen displays real-time performance data for the solar array. Optional CANADIAN SOLAR 455W solar panels offer high 22.8% efficiency, excellent durability, and cost-effectiveness with an appealing payback period. With a heavy snow load capacity of 5,400Pa and a wind load of up to 2,400Pa, they are ideal for domestic, agricultural, or garden office installations. The panels feature a black frame and come with a 30-year product warranty. Optional Hyundai HY6500SEi 6600W Petrol Inverter GeneratorThe Hyundai HY6500SEi is a premium portable generator, providing a reliable and economical power source.
