Residential-scale battery bank.        Most three-phase hybrid inverters require expensive high-voltage battery banks — stacks of cells running at 400V or higher, with limited consumer-retail options and significant up-front cost. The Deye SUN-20K-SG05LP3-EU-SM2 takes a different approach: it delivers a full 20kW three-phase output while running on a 48V low-voltage battery system. That means you can build a commercial-grade three-phase installation using the same mass-market 48V lithium batteries that residential systems use — Hubble, Pylontech, Sunsynk and similar units that are widely stocked and competitively priced across the South African market.        This is a serious piece of hardware. 20kW rated AC output across three phases (220\/380V or 230\/400V), up to 26kW of solar PV input across two MPPT trackers, 97.6% maximum efficiency, and a 350A maximum charge\/discharge current that pushes power into and out of the battery bank fast enough to handle real-world load swings. The inverter operates in hybrid, on-grid, off-grid, and UPS backup modes, with sub-10ms switching when the grid drops out. 100% unbalanced output means you can pull up to 50% of rated power from a single phase — useful where loads aren't cleanly distributed across the three phases (which, on most South African sites, they aren't).        For installers stepping up to bigger sites, the parallel capability is the real game-changer: up to 10 inverters can run in parallel, scaling the total system to 200kW of three-phase output for genuinely large commercial deployments. AC coupling means you can also retrofit this unit into existing solar installations rather than building from scratch.        Typical deployment scenarios:        \tLarge residential homes with three-phase grid connections and high simultaneous loads (geysers, multiple aircons, pool\/borehole pumps, EV charging)  \tSmall to medium commercial sites — workshops, retail outlets, light manufacturing, offices, guesthouses  \tAgricultural installations — pump houses, sheds, processing facilities  \tMulti-tenant residential — small estates, apartment blocks running shared backup  \tSolar retrofit projects — AC-coupled into existing single-phase or three-phase PV systems  \tPhased commercial rollouts — start with one unit, parallel additional units as the load and budget grow        Key Features        \t20kW three-phase output (220\/380V or 230\/400V) with 100% unbalanced output per phase  \t48V low-voltage battery system — uses mainstream lithium batteries (Li-ion or AGM\/GEL)  \t350A maximum charging\/discharging current — fast battery cycling  \t2 MPPT trackers, up to 26kW PV input — solar-ready out of the box  \tUp to 97.6% maximum efficiency, MPPT efficiency \u0026gt;99%  \tHybrid, on-grid, off-grid, and UPS modes with sub-10ms grid-loss switching  \tAC coupling — retrofit-ready into existing solar installations  \tParallel up to 10 units — scales to 200kW total system capacity  \tSingle-phase to three-phase conversion capability (with proper installation)  \tIP65 rated — suitable for outdoor installation  \tSiC MOSFET-based design for a compact form factor relative to power output  \tIntelligent air cooling, operating temperature range -40°C to +60°C\u003c\/p\u003e","brand":"GUNMANSA","offers":[{"title":"Default Title","offer_id":51577294192955,"sku":null,"price":68511.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/3480\/8379\/files\/D1.png?v=1787488021","url":"https:\/\/gunmansa.co.za\/ga\/products\/deye-three-phase-lv-hybrid-inverter-20kw","provider":"GUNMANSA","version":"1.0","type":"link"}
