OSM Residential Energy Storage Systems (ESS)
OSM Residential Storage Solutions (ESS) offer a wide variety of products to create and manage resilient energy infrastructures at an optimal cost. ESS offers two primary use cases. The first is creating utility-independent, solar-powered homes (residential ESS). On a larger scale, the second use case is utility supplementing generated power during periods of high demand (utility-scale ESS).
Older generation residential solar energy systems are tied to the utility power grid via inverters, which convert power from solar panels to AC electrical power during daylight hours. Marketable excess power might be sold back to utility companies. However, during the hours of darkness, the end-user is relying on the utility’s electricity supply. Utility companies are aware of these limitations and adjust their pricing models accordingly. Residential customers pay based on “time-of-use” rates, which are higher when solar power is not available.
Behind-the-meter ESS is utilized at this point. The electricity that is collected via solar panels charges batteries, the energy is then stored. When using these batteries with an inverter, the demand for AC power can be fulfilled at any time.
OSM48100 comes with two different product models, OSM48100P and OSM48100S, to support both P is a battery unit allowed you parallel more unit to increase the system capacity. While P will possible to connect in Series to increase the battery system DC voltage.
Beside the battery system. OSM also offer related solar charging controller based on different voltage and current. Custom can easy just connect all component together and start to use the whole system.

BATTERY MANAGEMENT IN ESS
In ESS, a battery management system fulfills two main functions, namely battery protection and battery monitoring.
Detecting a variety of fault conditions and protecting the battery from damage during the charging and discharging process is the main purpose and functionality of a BMS. Operating a battery outside of its specifications causes damage to the battery cells and leads to battery failure, producing maintenance efforts, and significant cost impact. Batteries must be closely monitored during charging and discharging to avoid these negative effects.
Protection must be provided against:
- Inrush current
- Reverse currents
- Short circuits
Those designing with OSM’s solutions will benefit from:
- Wider SOAs
- Short-circuit protection with higher peak current rates
- Turn-on and turn-off solutions tailored to application requirements
- Cost-efficiency resulting from a reduced BOM count and more effective parallelization solutions
A battery must be monitored systematically, to protect it. The battery management system is in charge of monitoring each of the cells in a battery pack and ensures that they are operated within the safe operating range. Various parameters, such as cell voltage, SOC, state of health (SOH), and the temperature, have a decisive impact on the performance, safety, and lifetime of batteries. A battery needs to be protected against possible external faults that would put the system in danger. Protecting the battery from damage during the normal function of the system (charging and discharging process) is one of the main functionalities of a BMS. Within Infineon’s product portfolio, designers will find the right devices to disconnect the battery system in case a fault is detected, thereby protecting its value. They will also help to detect system faults like overcurrents and short circuits.
