PV Generation Profile
Array rating, expected daily production, seasonal variation, charge-controller limits and periods of low generation.
Energy Storage & Electric Mobility
Custom Battery Systems for Solar and PV Energy Storage
As a custom solar energy storage battery manufacturer, Stellova develops systems around generation profile, daily load, required autonomy, charge and discharge power, inverter interface, operating environment and service strategy.
ENERGY SYSTEM DEFINITION
Start With Generation, Load and the Required Operating Strategy
A useful storage specification cannot be derived from panel power or battery capacity alone. The first review should combine site irradiation assumptions, load timing, critical loads, grid or generator availability, autonomy target, allowable cycling window and the actual power-conversion equipment.
WHAT TO DEFINE
Inputs for the First Solar-storage Review
Measured generation and load data are preferred. Where a project is early, documented assumptions can be used and then checked during system validation.
Load Profile
Day and night consumption, continuous and peak power, motor or inverter starts, critical loads and allowable load shedding.
Autonomy & Operating Mode
Required hours or days of support, on-grid or off-grid operation, generator interaction, backup reserve and target depth of discharge.
Site & Integration
System voltage, inverter and controller models, installation space, indoor or outdoor location, ambient temperature, ventilation, monitoring and service access.
ENGINEERING CONSIDERATIONS
Energy Capacity, Power Capability and Control Logic Must Align
Daily energy balance determines capacity, while peak loads, PV charging and inverter behavior determine current capability. Cell configuration, BMS logic, thermal management and system controls should be designed from the same operating model.
Energy Balance & Autonomy
Model usable energy from generation, consumption, conversion losses, reserve policy and seasonal conditions rather than nominal capacity alone.
Charge & Discharge Capability
Coordinate PV charge current, inverter demand, peak loads, generator charging and low-generation recovery with cell and BMS limits.
BMS & Power-conversion Interface
Define voltage windows, contactor and pre-charge behavior, SOC/SOH, alarms and communications with the inverter, controller or energy-management system.
Thermal & Mechanical Design
Address daily cycling heat, low-temperature charging, cabinet airflow, ingress exposure, module serviceability, cable routing and installation constraints.
SOLAR-STORAGE SYSTEM DEFINITION
Parameters Defined From Generation, Load and Operating Strategy
No fixed reference configuration is published on this page yet. The battery is engineered for the target equipment; voltage, capacity, continuous and peak current, charging, BMS logic, communication, protection rating and mechanical interfaces can be customized. Final specifications are subject to the approved project definition. Solar-storage sizing requires the site generation profile, load profile, autonomy target, inverter or PCS interface and operating strategy.
Project parameterHow it is defined
System voltage & energyDefined from the equipment voltage window, duty cycle, runtime or autonomy target and reserve. Continuous current | Defined from sustained operating loads and the required thermal margin. Peak current & duration | Defined from startup, acceleration, actuator or fault events with an explicit pulse duration. Charging interface | Defined from charger or power-source voltage, current, connector, control and recharge window. BMS & communication | Protection, sensing, SOC/SOH and CAN, RS485, RS232 or application-specific interfaces as required. Protection & environment | Ingress, vibration, shock, temperature, storage and corrosion requirements are assigned from the real operating environment. Mechanical integration | Enclosure, mounting, connector, cabling, service access and replacement method are developed around the equipment. Customization note | No fixed reference configuration is published on this page yet. The battery is engineered for the target equipment; voltage, capacity, continuous and peak current, charging, BMS logic, communication, protection rating and mechanical interfaces can be customized. Final specifications are subject to the approved project definition.
VALIDATION & SYSTEM READINESS
Validate the Battery Across the Solar Operating Cycle
Testing should reflect charging from variable generation, load changes, reserve behavior and recovery after low state of charge. The battery and power-conversion equipment must be evaluated together.
Battery Bench Test
Confirm capacity, charge and discharge limits, voltage behavior, protection thresholds, balancing, communication and thermal response.
Inverter-controller Integration
Check voltage windows, pre-charge, contactor sequence, charge commands, SOC reporting, alarms and recovery from faults.
Operating-cycle Test
Reproduce representative generation and load periods, including peak demand, low-generation recovery and backup-reserve behavior.
Production Release
Freeze the approved configuration, interface version, installation checks, acceptance criteria and production test plan.
FROM ENERGY MODEL TO RELEASED SYSTEM
One Definition Across Battery and Power Electronics
Stellova translates the site's generation, load and autonomy requirements into battery architecture, coordinates the BMS and power-conversion interfaces, defines validation and carries the accepted configuration into controlled production.
