30kW 60-90kWh All-in-One
C&I Energy Storage System
BSLBATT ESS-GRID DyniO is a 30kW all-in-one C&I energy storage system designed for small commercial facilities, island microgrids, farms, and remote sites that need reliable power without assembling separate components. The system integrates a three-phase hybrid inverter, BMS, EMS, and 62 to 93kWh of modular LiFePO4 battery capacity in a single plug-and-play cabinet. DyniO switches from grid to off-grid mode in under 5ms and supports diesel generator hybrid operation, making it well suited for locations with unstable or no grid access. Up to three units operate in parallel for 90kW total output. A 15kW variant (39 to 54kWh) is also available.
ESS-GRID DyniO Series: C&I All-in-One Energy Storage
ESS-GRID DyniO is designed for small and medium C&I microgrids. The system accepts PV input, includes a built-in EMS, and provides off-grid switching to keep critical loads powered during outages.
All components ship pre-wired in a single cabinet. Installers connect PV, grid, and loads without matching separate components or configuring communication protocols on site, reducing commissioning time significantly.
Battery capacity scales by adding or removing HV packs within the same frame. The 30kW platform offers five configurations from 62 to 93kWh; the 15kW platform offers four from 39 to 54kWh.
DyniO supports up to three units in parallel, diesel generator hybrid operation, and on/off-grid transfer in under 5ms. With 97.8% conversion efficiency and a -30 to 60°C operating range, it suits continuous operation in demanding C&I environments.

Multiple Power & Capacity Combinations
The ESS-GRID DyniO Series offers two inverter platforms with scalable battery capacity. Add or remove HV battery packs to match your site's energy requirements without changing the inverter or cabinet frame.
- 30kW (INV C30): 62kWh, 69kWh, 77kWh, 85kWh, or 93kWh
- 15kW (INV C15): 39kWh, 46kWh, 54kWh, or 62kWh
Each HV battery pack provides approximately 7.8kWh of rated energy. The 30kW platform uses 8 to 12 packs, while the 15kW platform uses 5 to 8 packs.
AC-Side Parallel Expansion to 90kW
Connect up to three DyniO units on the AC side for parallel or off-grid operation. A three-unit cluster delivers 90kW of rated output, serving larger C&I loads from a single coordinated system. Each unit operates independently with its own BMS and EMS, ensuring continued operation if one unit requires maintenance.
Off-Grid Switching and Diesel Generator Hybrid
DyniO transfers from grid-connected to off-grid mode in under 5ms, keeping critical loads powered during outages without noticeable interruption. The system also accepts diesel generator input, allowing hybrid operation at sites where grid power is unavailable or unreliable.
In diesel hybrid mode, the battery absorbs excess generator output and supplements the generator during peak demand. This reduces fuel consumption, limits generator runtime, and extends generator service intervals. For island microgrids and remote sites, the combination of PV, battery, and diesel provides energy security across varying load conditions.
Built-in Energy Management System
The ESS-GRID DyniO includes an integrated EMS that coordinates battery charging, PV input, grid interaction, and load output. Communication interfaces include RS485 for EMS and CAN/RS485 for battery management, plus two digital input and two digital output channels (DIDO) for external signal integration.
Remote monitoring enables real-time visibility into system status, battery SOC, power flow, and fault alerts. Operators can manage energy scheduling, peak shaving strategies, and generator coordination from a centralized platform.
Who Is the ESS-GRID DyniO Designed For?
The DyniO 30kW all-in-one system is built for sites that need integrated storage without the complexity of assembling separate inverter, battery, and control components.
Small C&I Facilities
Retail stores, office buildings, and light manufacturing sites use DyniO to reduce peak demand charges and increase solar self-consumption. The built-in EMS automates charge and discharge scheduling around time-of-use tariffs, helping site owners lower electricity costs without manual intervention.
Island and Off-Grid Microgrids
Remote communities and island installations where grid power is unavailable or unreliable. DyniO coordinates PV, battery, and diesel generator input in a single cabinet, simplifying logistics and commissioning. The under-5ms off-grid switching ensures uninterrupted supply to essential services such as water treatment, lighting, and communications.
Agricultural Operations
Farms and greenhouses with variable loads from irrigation pumps, cold storage compressors, and processing equipment. The 150% overload capacity handles motor starting surges that would trip a standard inverter. Modular battery packs let operators scale capacity to match seasonal energy demand changes.
Telecom Towers and Remote Infrastructure
Sites that currently rely on diesel generators for primary power. DyniO absorbs excess generator output during low-demand periods and covers base loads from stored solar energy, reducing fuel consumption and extending generator service intervals. The compact 590 x 713mm footprint fits inside standard telecom equipment shelters.
Small Data Centers and Cold Storage
Facilities running 24/7 critical loads where even brief power interruptions cause data loss or product spoilage. DyniO provides peak shaving to reduce demand charges during high-rate periods and instant backup power during grid outages.
Frequently Asked Questions About the ESS-GRID DyniO C&I Energy Storage System
Q: What is a C&I all-in-one energy storage system?
BSLBATT defines a C&I all-in-one energy storage system as a single-cabinet solution that integrates a three-phase hybrid inverter, battery management system (BMS), energy management system (EMS), and modular LiFePO4 battery packs. Unlike separate-component setups, an all-in-one system arrives pre-wired and pre-configured, reducing installation time and eliminating inverter-battery compatibility issues.
Q: How fast does the DyniO switch between grid-connected and off-grid mode?
BSLBATT ESS-GRID DyniO completes the grid-to-off-grid transfer in under 5 milliseconds. This seamless switching keeps critical loads powered during grid outages without noticeable interruption to connected equipment. The system also supports fast switching back to grid-connected mode when utility power returns.
Q: Can the ESS-GRID DyniO operate with a diesel generator?
BSLBATT ESS-GRID DyniO supports diesel generator hybrid operation. The system coordinates battery discharge and generator output to reduce fuel consumption and limit generator runtime. In diesel hybrid mode, the battery absorbs excess generator power and supplements the generator during peak demand, extending service intervals and lowering operating costs.
Q: How many DyniO units can operate in parallel?
BSLBATT supports up to three ESS-GRID DyniO units in AC-side parallel operation, providing a combined output of 90kW (with INV C30). Each unit operates with its own BMS and EMS, allowing the system to continue operating if one unit is taken offline for maintenance.
Q: What applications is the ESS-GRID DyniO best suited for?
BSLBATT ESS-GRID DyniO is designed for small and medium C&I sites including retail and office buildings, island microgrids, agricultural operations, telecom towers, and temporary sites such as construction or mining camps. The system is particularly well-suited for locations with unreliable grid access where diesel generator hybrid operation and off-grid switching are needed.
Q: Is the ESS-GRID DyniO rated for outdoor installation?
BSLBATT ESS-GRID DyniO carries an IP20 protection rating and is designed for indoor installation or placement within a weatherproof enclosure. For projects requiring outdoor-rated C&I storage without additional enclosures, BSLBATT offers IP55-rated alternatives including the ESS-GRID C225/C241 and ESS-BATT Cubicon Lite.
