EG4 48V Lithium Battery Starter Kit (Up to 30.72kWh)

Customizable Energy Storage Built for Easy Scale-Up

Take full control of your power security with the ultimate foundational energy storage package. The EG4 48V Lithium Battery Starter Kit is the perfect solution for homeowners, contractors, and solar enthusiasts building a system engineered for seamless expansion.

Instead of dealing with mismatched components, this complete starter kit gives you the flexibility to choose your preferred battery chemistry profile, select the perfect enclosed cabinet size, and deploy up to 30.72kWh of raw, reliable power backup. It provides an enterprise-grade, plug-and-play storage infrastructure that integrates flawlessly with premium off-grid and hybrid inverters.

## Step 1: Choose Your Lithium Battery Profile ($LiFePO_4$)

Each module delivers 48V (51.2V Nominal) / 100Ah / 5.12kWh of stable power, rated for over 6,000–7,000 deep cycles.

• Option A: EG4 LifePower4 V2: The ultimate budget-friendly workhorse. Engineered with Tier-1, A+ prismatic cells and an advanced internal BMS. The V2 model features enhanced heavy-duty dual terminals (two positive, two negative) for effortless wiring and auto-addressing capability.

• Option B: EG4 LL-S: The premium, intelligent flagship module. It includes a built-in HD LCD touch screen to monitor internal cell voltages, SOC, temperatures, and active alarms in real-time. It features dual on-board fire arrestors for thermal runaway defense, emergency E-Stop rapid shutdown compliance, and an EMP-hardened design.

## Step 2: Select Your Heavy-Duty Enclosed Server Rack

Ditch the messy wall-mounts. Keep your power bank organized, ventilated, and completely secure.

• EG4 3-Slot Enclosed Rack: Holds up to 3 batteries (15.36kWh total). A compact, heavy-duty welded steel cabinet featuring pre-installed 300A paralleling busbars with protective covers, top/side cable knockouts, a lockable vented door, and removable casters for easy positioning under tight spaces.

• EG4 6-Slot Enclosed Rack: Holds up to 6 batteries (30.72kWh total). Built for full-scale whole-home setups or commercial estates. Features heavy-duty, high-capacity paralleling busbars, integrated grounding wire layouts, and lockable security panels.

## Key Performance Benefits

• Massive Scalability: Whether you start small with 1 or 2 batteries inside a larger cabinet, this kit allows you to add identical modules easily over time. You can scale a single rack up to 30.72kWh, and parallel up to 64 batteries total while maintaining complete closed-loop BMS telemetry.

• Advanced Closed-Loop Communications: Automatically communicates directly with major inverter brands (including EG4, Deye, Sol-Ark, Victron, and Schneider). The master battery continuously directs the inverter’s charging profile based on temperature and cell health, maximizing battery life up to 15+ years.

• Heavy-Duty Power Transfer: All kits come optioned with premium, heavy-strand 2/0 AWG or 4/0 AWG battery cables sized specifically to handle the massive current draw of a fully loaded cabinet safely without voltage sags or overheating.

• Visual Status & Total Protection: Full circuit isolation with individual heavy-duty breakers on each battery. Built-in diagnostic software guards against cell over-voltage, under-voltage, short-circuits, and extreme temperature conditions.

## Technical Specifications Overview

• System Voltage: 48V DC / 51.2V Nominal

• Capacity Per Battery: 100Ah / 5.12kWh

• Max Continuous Discharge Current: 100A per battery module

• Cabinet Construction: Heavy-duty, powder-coated steel with lock keys and heavy-duty swivel casters.
