EG4 WallMount Indoor Battery 280AH | 51.2V | Indoor | Heated UL1973, UL9540A |

The WallMount Indoor 14.3kWh batteries are ideal for low-voltage residential indoor energy storage applications. The batteries use lithium iron phosphate cells with the highest safety performance and an intelligent Battery Management System (BMS) that can monitor and record the voltage of each cell along with the current, voltage, and temperature of the module in real-time. The BMS also contains a passive balance function and an advanced battery control method, both of which improve the performance of the battery pack.

ON-BOARD LCD TOUCH SCREEN

Easy to see BMS monitoring, and selectable closed-loop communications with EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye inverters.

DUAL ON-BOARD FIRE ARRESTORS

Offer fail-safe protection against thermal runaway.

INTEGRATED SELF-HEATING FEATURE

Internal heating keeps cells operating during cold temperatures.

INTEGRATED BUSBARS

The battery design comes manufactured with 600A internal busbars with multiple terminals (4 positive & 4 negative) eliminating the need for external busbars when paralleling batteries and/or multiple inverters.

INNOVATIVE EMERGENCY STOP FUNCTION

The optional ESS disconnect can shut down all batteries and inverters (if equipped with rapid shut down capability) with the press of a button.

THE PERFECT PARTNER TO EG4 INVERTERS

The optional conduit box mates up directly to the connection ports of EG4 inverters allowing a sleek and efficient installation. For other inverters or stand-alone battery installation, the conduit box plugs should be installed.

EG4 48V Chargeverter GC INV029

Fits my needs

Installed this to use with a generator that was not compatible with my victron multiplus. This allowed me to keep my generator and use it for a backup supply to charge my EG4 batteries. I did not like the fact that when you adjust the current limit the charger resets to 0 and then ramps up instead of just going to the new setpoint from where it currently is.

Thank you for a great product.

Need more in depth instructions

Moe in depth instructions would be great, i had an issue with input voltage too high, charger sensed it and would not charge batteries. Also had no fault lights or anything. There are lights you can see on the diodes on the side of the charger that will tell you it's not happy. I Figured it out the hard way. Other than some early growing pains it works great

A Real Work Horse

I put this engine on my duck boat and it performs so much better than the predator 420 engine I had on the boat. This 500cc runs smoother and has a lot more horse power and torque and runs at a higher RMP than the predator engine. I'll definitely be using these DuroMax 500cc engines for other projects!!

Excited so I pre-ordered

Although these are not in stock yet, this will be the best fit for my home. I have a 2200 sq foot house and was worried I would not have enough to power the A/C during a power outage along with the well pump and sump pump. I called in to make sure I had the right fit and Alex was so helpful and kind. He went out of his way to make sure everything was the right fit. This generator will hookup to my homes natural gas line, which is also what I wanted.
