Overview

A Prefabricated Energy Block for Solar-Diesel Hybrid Projects The container combines 1.4MWh LFP battery storage, power conversion and PV input in one prefabricated equipment package. It provides 750kW rated AC input/output power and up to 720kW PV input. On the project side, the container works with the site AC bus, industrial loads, the utility grid and an existing or planned diesel generator according to the approved electrical design. The configurable 1000kW STS is a separate outdoor cabinet rather than standard equipment inside the main container. For background on containerized storage formats and purchasing considerations, see the BESS container guide.

What It Solves

Multi-Equipment Integration

Battery storage, PCS and PV input are combined in one prefabricated container, reducing the number of separate equipment packages that must be coordinated on site.

MWh-Scale C&I Storage

The 750kW / 1.4MWh configuration gives EPCs and project owners a defined starting point for large commercial and industrial energy projects.

Hybrid Microgrid Planning

The system provides a storage and power-conversion base for projects that combine solar PV, grid supply, industrial loads and diesel generation.

Grid and Off-Grid Configuration

A separate 1000kW STS outdoor cabinet can be included when the approved project architecture requires grid-connected and off-grid operating modes.

Prefabricated Container Delivery

The main energy equipment is supplied as a prefabricated container package. Foundation, cabling, protection coordination and commissioning remain part of the project design.

Dedicated PCS path for each battery cluster with cluster-level management

Cluster-Level Power Conversion

One PCS per Battery Cluster

Defined Cluster-to-PCS Relationship

Each battery cluster is paired with its own PCS path rather than relying on one common conversion stage for several parallel clusters.

BMS and PCS Integration

Battery monitoring and power conversion are coordinated within the cluster architecture. Final control settings are established during project engineering and commissioning.

Clearer Cluster Management

The architecture provides a defined cluster-level control structure for project design and operation.

Project-Dependent Grid Configuration

Optional 1000kW STS Outdoor Cabinet

Main BESS container with separate optional 1000kW STS outdoor cabinet

Separate Outdoor Cabinet

The STS is planned as an independent outdoor cabinet alongside the main energy storage container.

Grid and Off-Grid Architecture

The STS can form part of the approved switching architecture for projects that need more than one operating mode.

Engineering Review Required

Switching sequence, generator coordination, protection settings and site interfaces are confirmed from the project electrical design.

Applications

MWh-Scale Storage for Hybrid Microgrids and Large C&I Sites

A defined storage, PCS and PV-input platform for projects that coordinate solar generation, grid supply, industrial loads and diesel generation.

Solar-diesel microgrid, weak-grid industrial, mining, large C&I solar and temporary infrastructure applications

Solar-Diesel Hybrid Microgrids

For EPCs and system integrators that need to combine PV, battery storage and an existing or planned diesel generator within one project architecture. Generator sizing, interface and control logic are confirmed for the site.

Weak-Grid and Off-Grid Industrial Sites

For industrial projects where grid availability or operating mode requires a site-specific switching and protection design. The optional STS cabinet is evaluated as part of that design.

Mining and Remote Infrastructure

For remote industrial loads that use a mix of solar generation, stored energy, grid supply where available and diesel generation. Fuel savings and backup duration depend on the project load and operating strategy.

Large C&I Solar Storage

For factories, industrial parks and large commercial facilities that need an MWh-scale battery and PCS configuration alongside a substantial PV system.

Construction and Temporary Infrastructure

For projects that prefer a prefabricated container equipment package. Transport, foundation, cabling and recommissioning requirements are assessed for the intended site.

Actual PV capacity, generator data, load profile, backup objective and operating strategy must be reviewed before the final configuration is confirmed. See the KUNETIC Solar + Storage + Diesel solution for the wider project context.

Project Configuration Support

Define the System Around the Site Operating Plan

Load and Runtime Assessment

Provide the load profile, peak demand, critical loads and required operating duration so the 750kW / 1.4MWh configuration can be checked against the project duty.

PV Input Matching

Provide the planned PV capacity, operating voltage and array data for review against the 720kW maximum PV input and the specified voltage window.

Grid and Generator Interface Review

Provide utility conditions and generator specifications. Final connection, communication and control requirements are project-dependent.

STS and Operating Mode

Confirm whether the site requires grid-connected, off-grid or mixed operating modes so the separate 1000kW STS option can be evaluated.

Communication and Site Conditions

CAN, RS485 and WiFi are listed communication options. Final selection is reviewed together with ambient temperature, humidity, altitude and site access.

Regional Compliance Review

Provide the target market, grid-code requirements and required certifications before the commercial and technical configuration is finalized.

FAQ

The main container includes a 1.4MWh LFP battery system, a 750kW PCS, a 720kW MPPT section, liquid cooling and an IP54 enclosure. The diesel generator and the configurable 1000kW STS outdoor cabinet are external project equipment rather than standard equipment inside the container.

No. It is a separate configurable outdoor cabinet for projects that require a grid-connected and off-grid switching architecture. Its use and final electrical design are confirmed during project engineering.

The product can be configured as part of grid-connected and off-grid project architectures with the separate 1000kW STS cabinet. The switching sequence, protection settings and operating logic depend on the approved site design.

The product is intended for Solar + ESS + Diesel hybrid projects. Generator capacity, voltage, interface, communication and control requirements are reviewed for each project before the final configuration is confirmed.

Maximum PV input power is 720kW. The rated input voltage is 600Vdc, the MPPT range is 150V to 950V, and maximum input voltage is 1000Vdc. The final array design must also comply with the specified input-current and site conditions.

The stated value is 6,000 cycles at 25°C, using 0.5C charge and 0.5C discharge, 90% DOD and an end-of-life condition of at least 70% SOH. These conditions should be kept together when comparing cycle-life figures.
