🔋 What are Sunsynk low-voltage batteries
Sunsynk LV batteries are lithium-ion phosphate (LiFePO₄ / LFP) battery packs operating at nominal ~ 48 V (often 51.2 V nominal). bshockedelectrical.co.za+2solarsouthafrica.co.za+2
They are designed to pair with Sunsynk low-voltage inverters, for hybrid solar + battery + grid (or generator) setups — ideal for homes, small farms, small businesses — anywhere a standard 48 V battery bank is used. sbs-sa.co.za+2Vital Solutions+2
⚙️ Key Features & Capabilities
Battery chemistry & safety: LiFePO₄ (LFP), known for good thermal stability, safety and long life compared with older battery chemistries. solarsouthafrica.co.za+2shop.nnmenergies.co.za+2
Capacity options: Typical units include 5.32 kWh / 104 Ah at 51.2 V. greenhomesystem.co.za+2solarsouthafrica.co.za+2 Some models go up to ~10.24 kWh or more, depending on the configuration. shop.nnmenergies.co.za+2upstreamenergy.co.za+2
Built-in Battery Management System (BMS): Protection against over-charge, over-discharge, over-current, temperature extremes; also handles cell balancing and monitors battery health. solarenergyssa.co.za+2ngcolosigroup.co.za+2
Scalability: Multiple battery units can be connected in parallel — enabling larger storage banks if user needs grow. upstreamenergy.co.za+2sswarehouse.co.za+2
Form factor & installation flexibility: Many are wall-mountable or floor-stand design — compact enough for domestic energy rooms yet robust enough for solar-plus-storage installations. greenhomesystem.co.za+2solarsouthafrica.co.za+2
Cycle life and durability: Many units rated for ~6,000 cycles at ~80% depth of discharge (DoD) — offering long-term, reliable storage. bshockedelectrical.co.za+2upstreamenergy.co.za+2
🎯 Who They Are For — Typical Use Cases
Residential homes — small to medium houses using a 48 V battery bank and solar panels; ideal for reducing power bills, providing backup during outages, and maximizing self-consumption.
Small farms or rural properties — if you have modest loads (lighting, pumps, small appliances), LV batteries offer a dependable hybrid solar storage solution without the complexity or cost of high-voltage systems.
Workshops, small businesses or remote buildings — where there’s a need for solar + battery + grid (or generator) flexibility, but loads are moderate and a 48 V battery setup is sufficient.
Modular/expandable systems — because many models support parallel connection, clients can start with a modest battery bank and expand later as demand grows.
📦 Example Battery Option
Sunsynk 5.32 kWh 51.2 V LiFePO₄ Battery — compact 48 V-class battery, 104 Ah capacity, wall- or floor-mountable, modular for parallel expansion, ideal for residential solar storage or backup power systems.
For Deltool’s customers — especially homeowners, small farms or rural clients around Delmas/Mpumalanga — Sunsynk low-voltage batteries are often the most cost-effective and practical way to add storage to a solar installation. They’re safe, durable, scalable, and a good match for typical 48 V hybrid inverter systems.
