SYSTEM ARCHITECTURE

How Seplos 104-R 26kWh Server Rack LiFePO4 Battery System Manages Energy Across the System

A connected energy storage architecture coordinates solar generation, grid power, battery charging and critical loads to support more flexible and resilient energy use.

Solar PV Generation

Renewable energy is supplied to the site and excess generation can be directed to battery charging.

Utility Grid

Grid electricity supports the site when required and can be managed according to project strategy.

Seplos 104-R 26kWh server rack battery system

Seplos 104-R 26kWh Server Rack LiFePO4 Battery System BESS

Smart BMS and system controls coordinate charging, discharging, protection and energy dispatch.

Intelligent Energy Control

Essential Loads

Stored energy can help reduce peak demand, shift energy use and improve renewable energy utilization.

Critical Backup Loads

Selected equipment can receive stored power during grid interruptions, subject to system configuration.

Peak Shaving

Reduce high-demand grid consumption

Solar Self-Consumption

Store excess solar energy for later use

Backup Power

Power essential loads during outages

STEP 01

Energy Input

Solar PV and grid sources supply power according to site conditions.

STEP 02

Smart Coordination

BMS and control logic monitor system status and available energy.

STEP 03

Storage & Dispatch

Energy is stored or released based on demand and project strategy.

STEP 04

Load Support

Commercial and critical loads receive power through the configured system.

RECOMMENDED APPLICATIONS

This Residential Energy Storage is designed for energy storage projects requiring flexible capacity, intelligent battery management and reliable power support.

Solar Self-Consumption Optimisation

Store excess solar energy during the day and use it at night to make better use of your solar power.

Backup Power During Grid Outages

Keep essential home appliances running when the grid goes down, providing reliable backup power when it matters most.

Time-of-Use Arbitrage(Peak Shaving)

Store electricity when rates are low and use it during peak-price hours to help reduce energy bills.

Off-Grid & Energy Independence

Power your home with stored energy and solar generation to reduce reliance on the grid or support off-grid living.

SYSTEM INTEGRATION

System Compatibility & Project Integration

System voltage, communication protocol, inverter settings and site requirements should be confirmed before final configuration and ordering.

ENGINEERING REVIEW

Confirm Compatibility Before Final System Configuration

The final energy storage configuration depends on inverter compatibility, system voltage, communication protocol, load profile and the required backup duration.

COMMUNICATION

CAN / RS485

Communication settings should match the selected inverter, EMS and project control requirements.
