Problem
Farms and other commercial operations face high and volatile electricity costs, expensive diesel generator reliance, and limited grid capacity that can require costly Distribution Network Operator (DNO) upgrades. These factors create unpredictable energy expenses and risk of power interruptions that threaten operational margins.
Solution
WattBox delivers a rugged, containerised energy hub that combines solar generation, modular battery storage, and optional generator integration into a single pre‑built system. The solution can be configured for grid‑tied or off‑grid operation, supports single‑ or three‑phase loads, and scales from 10 kW to 350 kW solar and 32 kWh to 416 kWh of storage. By storing excess solar and charging the batteries during low‑cost tariff periods, WattBox reduces peak‑demand charges and enables time‑of‑use optimisation. Surplus energy can be exported back to the grid, while the battery automatically supplies power during outages, protecting critical equipment without diesel. The system is designed to integrate with existing solar panels and can be delivered ready‑to‑use, eliminating the need for extensive on‑site engineering.
Target Audience
WattBox is aimed at medium to large farms, agricultural enterprises, and other commercial sites that require reliable, cost‑effective power and want to minimise diesel generator use and grid dependency.
Features
- Modular battery banks (32 kWh‑416 kWh) that scale with farm energy demand
- Solar generation capacity from 10 kW to 350 kW, compatible with rooftop or ground‑mounted arrays
- Grid‑tied or fully off‑grid configurations, including single‑ and three‑phase options
- Integrated MPPT solar chargers, inverters, and 48 V battery management for efficient energy conversion
- Automatic backup switching to battery (and optional generator) during grid outages
- Time‑of‑use optimisation: charge batteries when electricity is cheap, discharge during peak periods
- Ability to export surplus power to the grid, reducing overall energy spend
- Pre‑built, containerised design for rapid on‑site deployment without major construction
