The EG4 GridBOSS 200A MID is a power gateway and microgrid interconnection device (MID). It gives a home one point of management for grid, solar, and battery power.
Here are 12 things to know about its ratings, ports, and features.
The EG4 GridBOSS, Demystified
1. It’s an MID
The EG4 GridBOSS is an MID, or “microgrid interconnection device,” which basically means it is a central hub through which a home’s power can be managed. It’s like one touchpoint for all of your home’s power inputs and outputs, to keep things as simple as possible. This means it can manage power from the grid, and if your home has an alternative energy system, like a solar energy system, it can manage power to and from that system and the grid as well.
2. It Has a 200A Service Entrance Rating
The product page lists a 200A service entrance rating. Many homes have 100A to 200A service, so the EG4 GridBOSS fits a wide range of homes. It combines many components into one unit, which reduces the number of separate parts. Breakers are sold separately.
3. It Works With Off-Grid and Grid-Tied Systems
A single point of central control for a home’s energy is not just beneficial to off-grid systems that are powered by solar or other sources; it can also be useful for homeowners on the grid as well. In particular, it is a great solution for grid-tied systems that are also served by backup energy solutions such as solar power.
A grid tied solar system with battery backup can use the EG4 GridBOSS to manage power between the grid, solar, and batteries. It supports AC coupling, so it also suits a grid tied solar battery backup setup. See BigBattery’s grid-tied battery backup systems or its off-grid solar systems.
4. It Pairs With an EG4 Solar Inverter
The EG4 GridBOSS does not replace your inverter. The product page lists the EG4 12kPV, EG4 18kPV, and EG4 FlexBOSS21 as supported inverters. Browse all BigBattery solar inverters.
5. It Can Handle Up to 3 Inverters
The EG4 GridBOSS has 3 inverter ports, so it can manage more than one inverter in a larger system.
6. It’s Fairly Lightweight and Compact
This microgrid interconnection device is only 55 lbs and is fairly compact, at 31.5″x19.7″x7″.
7. It’s Easier to Install
It combines many components into one unit, which can simplify hanging and wiring.
8. It Has a Generator Input
Because of this it is compatible with grid-tied systems that are equipped with gas generators as a hedge against blackouts.
9. It Consolidates Up to 10 Components Into One Unit
Homeowners often have to invest heavily in switches, wiring, and other components in order to have an electrician install a suitable and safe system that meets electrical codes. The EG4 GridBOSS simplifies that by combining up to 10 of these components into one system that can easily be managed or repaired, and which is easy to troubleshoot if something goes wrong, since one entity made the whole thing.
10. It Features Smart Load Management With 4 Smart Load Ports
These smart load ports let you choose appliances or circuits that you want to be able to shed whenever the system is under heavy utilization. For instance, you can allocate the water heater for smart load management so that it can be automatically shut off if needed. The EG4 GridBOSS has four programmable smart load ports.
11. It Empowers Real-Time Monitoring and Can Be Remotely Managed
You can easily monitor the performance of the system or make adjustments to smart load management since the entire thing is so versatile. It monitors energy flow across up to eight circuits and communicates over RS485, CAN bus, and Wi-Fi. Moreover, it’s even capable of being remotely controlled via Wi-Fi.
12. It Reduces the Number of Separate Parts You Buy
It reduces the number of separate parts you buy. Breakers are sold separately, so ask BigBattery what your install needs.
