The EG4 GridBOSS MID V2 System is a modular energy storage solution designed for residential and commercial applications. It integrates advanced lithium iron phosphate (LiFePO4) battery technology with grid-tie capabilities, enabling peak shaving, load shifting, and emergency backup power. The system features scalable capacity (5kWh–30kWh), UL-certified safety protocols, and compatibility with solar inverters. Its MID (Modular Interconnect Design) architecture allows parallel expansion, while built-in battery management ensures thermal stability and cell balancing.
What distinguishes the MID V2 from previous versions?
The MID V2 introduces plug-and-play modular expansion and enhanced thermal management. Unlike earlier models requiring professional wiring, its snap-lock connectors enable DIY capacity scaling. The upgraded cooling system maintains cells within ±2°C of optimal 25°C, crucial for maximizing LiFePO4 cycle life beyond 6,000 cycles.
Beyond basic specs, the MID V2’s dynamic voltage compensation automatically adjusts for line losses in long cable runs. Imagine powering a remote shed: traditional systems suffer voltage drops, but the V2 maintains stable 48V output regardless of distance. Pro Tip: Pair with EG4’s 12kW hybrid inverter for seamless solar integration—third-party inverters may lack necessary communication protocols.
| Feature | MID V1 | MID V2 |
|---|---|---|
| Max Parallel Units | 4 | 8 |
| Cycle Life | 4,500 | 6,000+ |
| Warranty | 5 years | 10 years |
How does grid interaction work?
The GridBOSS utilizes bidirectional inverters for real-time energy trading. During peak rates, it sells stored solar power back to utilities at 2x-3x standard buyback rates through automatic TOU (Time-of-Use) optimization. Why leave money on the table when algorithms can monetize every kWh?
Practically speaking, the system’s 72-hour island mode keeps essentials running during outages. A 30kWh configuration can power a 3-bedroom home’s fridge, lights, and WiFi for 4 days. Pro Tip: Enable “Storm Watch” mode when severe weather alerts activate—the system pre-charges to 100% using grid power before outages occur.
| Scenario | Energy Use | Backup Duration |
|---|---|---|
| Basic Loads | 2kW | 15 hours |
| Full Home | 7kW | 4.3 hours |
| Emergency Only | 500W | 60 hours |

FAQs
No—it uses proprietary CAN bus communication. Mixing brands voids warranties and risks equipment damage.
Can it power 240V appliances?
Yes, through the companion 48V-to-240V inverter. Ensure continuous loads stay under 12kW to prevent overloads.
