Project Overview
Location: Peru | Date: 2024
Capacity: 300KW | Application: Agricultural (Heavy Equipment)
A 300KW large-scale off-grid solar system was deployed at an industrial farm in Peru to power grain dryers, conveyor belts, and hydraulic press equipment that previously relied on a dedicated diesel generator plant.
The diesel plant had been consuming over 4,000 litres of fuel weekly. This is the largest project in the series, marking a milestone for the contractor's transition from commercial rooftop installations to heavy-equipment solarization.
Industrial Farm Electrification Barriers for EPC Contractors
Scaling off-grid solar to directly drive three-phase motors ranging from 30KW to 75KW presented exceptional technical demands. The farm's largest single load—a 75KW grain dryer fan—required a starting current nearly six times its running current, demanding inverter surge capacity that most commercial solar power systems could not sustain.
Beyond surge handling, the contractor needed to design a battery bank large enough to buffer the gap between solar generation and the farm's 6 AM pre-dawn drying shift.
The remote coastal desert location meant corrosive airborne dust, requiring all outdoor cabinets to meet IP54 ingress protection at a minimum. These cumulative requirements made a modular, high-capacity architecture essential.
The Anern Solution: Engineered for Installers
The contractor deployed three 105kW liquid-cooled ESS cabinets in parallel, delivering a combined 315kW of inverter capacity with liquid-cooled thermal management that maintained battery cell temperatures within 2°C despite the desert environment's 40°C daytime ambient.
Each cabinet's integrated 241kWh battery module eliminated the need for separate battery rack installation. For the grain dryer fan's inrush event, the system's parallel inverter topology shared the surge across all three units, keeping individual inverter loading below 110% rated capacity.
The contractor added a 125kW liquid-cooled ESS cabinet as a dedicated high-surge buffer for the farm's hydraulic press, bringing total system capacity to 420KW—providing comfortable headroom for simultaneous equipment operation during peak harvest season.
Multi-Cabinet Parallel Architecture & Load Prioritization
Anern's liquid-cooled cabinets were arranged in a master-slave configuration with automated load shedding logic. Critical equipment—grain dryers and conveyors—received priority power allocation from the 100kW commercial ESS cluster.
Lower-priority loads like workshop lighting and office air conditioning were served by the 225kWh commercial solar battery reserve. The entire 420KW array was managed through Anern's central EMS controller, which optimized charging schedules based on next-day weather forecasts and the farm manager's daily equipment schedule.
Key B2B Benefits & Project Impact
- Multi-MW Scalability with Liquid-Cooled Reliability: Three 105kW liquid-cooled ESS cabinets scaled seamlessly to 315kW (expandable to 1MW+), giving the EPC contractor a replicable design template without re-engineering per site.
- Heavy Motor Surge Handling Without Oversizing: Parallel inverter topology shared 75KW motor inrush across three units, eliminating the need to oversize the inverter bank by 2x—saving approximately 18% in capital equipment cost.
- All-in-One Integration Reduces Field Labor: Each liquid-cooled ESS cabinet integrated inverter, battery, BMS, and cooling in a single enclosure, cutting installation time by an estimated 35% compared to rack-based systems requiring field-assembled battery modules.
- Proven Reference for Industrial-Scale Agricultural Solar: The 300KW+ deployment serves as a powerful reference case for the contractor to bid on similar commercial industrial solar projects across Peru's agricultural sector.
