Vestwood 9.6kWh 48V 200Ah LiFePO4 Lithium Battery

Description Overview The Vestwood 9.6kWh 48V 200Ah LiFePO4 Lithium Battery (model VT48200B) is the largest residential battery in the Vestwood household range. It delivers 9.6kWh of LiFePO4 storage in a single rack-mountable enclosure — enough to power a typical 3–4 bedroom Kenyan home through a full overnight period without needing multiple batteries wired in parallel. One unit. One BMS. One set of cables. That’s the simplicity advantage of choosing the VT48200B over a multi-battery parallel setup.

Inverter Compatibility The VT48200B communicates via RS485, CAN, and Modbus protocols. It has been tested and confirmed compatible with: Deye (all 48V hybrid models) Growatt (SPF and SPH series) Sunsynk (5kW, 8kW, 12kW) SRNE (all 48V models) Victron (MultiPlus, Quattro, EasySolar) Luxpower Goodwe (ET and BT series) RCT, Synapse, Voltronic All Vestwood inverters (6kW, 10kW, 15kW, 20kW) Recommended inverter charge settings: Max charge voltage 56V, Float 54V, Cut-off 40.5V. Intelligent BMS — 7 Layers of Protection The self-designed Vestwood BMS protects the battery at every level: Overcharge protection — prevents damage from excessive charging voltage Over-discharge protection — stops deep drain that shortens cell lifespan Overcurrent protection — guards against excessive current draw Short circuit protection — instant disconnect in fault conditions Over-temperature protection — shuts down if cells exceed safe operating temperature Under-temperature charge lockout — prevents charging below 0°C (which damages LFP cells) Dynamic cell balancing — ensures all 15 cells charge and discharge evenly for maximum lifespan The BMS also provides real-time SOC (State of Charge) and SOH (State of Health) data via the communication interface — accessible through your inverter’s monitoring system or app. Installation Options The VT48200B supports three installation methods: Rack mounting — fits standard 19″ and 23″ server rack cabinets (professional look, space-efficient) Wall mounting — using heavy-duty brackets rated for 100kg (consult your installer) Floor mounting — on any stable, level surface (simplest option) Vestwood offers a dedicated single-layer battery rack (sold separately) for clean rack installations. When paralleling multiple VT48200B units, maintain at least 10mm spacing between batteries for adequate airflow. Important: At 78kg, professional two-person installation is mandatory. Do not attempt to lift or mount this battery alone. Expandable Up to 144kWh The VT48200B supports up to 15 units in parallel — a maximum of 144kWh on a single bus. This means you can start with one battery (9.6kWh) and expand over time as your needs or budget grow. Common expansion paths: 1 unit (9.6kWh) — standard 3–4 bedroom home 2 units (19.2kWh) — large home or small business with extended backup 3 units (28.8kWh) — commercial property with full overnight coverage 4 units (38.4kWh ) — industrial or large commercial applications Why Choose One 9.6kWh Unit Over Two 5kWh Units The VT48200B delivers clear advantages over a two-battery parallel setup: Simpler wiring — one set of cables instead of two Fewer failure points — one BMS instead of two Less wall space — single enclosure vs two mounted side-by-side Faster installation — one connection point to the inverter Better cell balance — all 15 cells managed by a single BMS for consistent performance The only scenario where two separate units are preferable is when BMS redundancy is critical (e.g., medical equipment backup) — if one unit fails, the other continues operating independently.
