Questions about this product
Questions about this product
What is the EG4 WallMount Indoor 14.3 kWh battery?
A 51.2 V, 280 Ah LiFePO4 wall-mount battery with LCD, integrated self-heating, dual fire arrestors, and 600 A internal busbars. Rated for over 8,000 cycles at 80% DoD, 10-year warranty, UL 1973 and UL 9540A.
What are the charge and discharge limits?
Max continuous charge and discharge are 140 A. EG4 recommends 60–140 A in normal use. The BMS trips around 200 A, so design wiring and protection accordingly.
What is the operating temperature range?
Charge 0 to 50°C. Discharge −20 to 55°C. Storage 0 to 45°C. Indoor rating is IP20.
Does it support closed-loop communication with my inverter?
Yes. Selectable CAN or RS485 with EG4 inverters and options for Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye. Protocols are set from the battery’s LCD.
How many can I parallel and do I need external busbars?
Using the built-in 600 A busbars, up to 3 batteries with one inverter, 4 with two inverters, or 5 with three inverters. Larger systems require external busbars and fusing sized at 200 A per battery. Do not series connect these batteries.

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.

To serve our customers across Canada, whether you're in a major city or completely off the grid, many of our products are shipped via freight delivery to ensure safe and efficient transport. Depending on your location and the item, you’ll have the option to pick up from a nearby warehouse terminal or request home delivery.
Free Terminal Pickup on Most Large Items
Most large items we sell, including appliances, solar kits, and other freight-shipped products, include free shipping to your closest warehouse terminal.
Your order will be delivered to the nearest terminal based on your location, where you can pick it up at your convenience.
Need it delivered to your home or cabin? We can set that up for you. There is a small additional fee for residential delivery.
Remote and Hard-to-Reach Locations
If you live in a remote area or outside standard freight zones, please contact us before placing your order.
Some rural locations may require additional charges or special delivery arrangements. We'll confirm everything with our freight partner before shipping.
Local Pickup Options Across Canada
We work with warehouse terminals in every province, so many of our products can be picked up locally to save on shipping costs.
Not all items are eligible, so if you're unsure at checkout, give us a call or send us an email and we'll confirm the best option for your area.

Receiving Freight Shipments
For large freight deliveries, you will receive a call from the carrier or your nearest terminal when your order is ready for pickup or delivery.
Important: Always inspect your shipment before signing any paperwork.
If the box or pallet is damaged:
- Do not sign the Bill of Lading (BOL) as "received in good condition"
- Instead, note the damage clearly on the BOL
- Or refuse the shipment if damage is significant
If no damage is recorded and the shipment is accepted, the freight carrier will consider it delivered in perfect condition. In that case, we cannot issue a refund or replacement. This is a strict freight carrier policy and applies to all deliveries.
Damaged or Missing Items
If there’s an issue with your shipment (whether it’s damage, missing parts, or anything unusual) please contact us within 48 hours of receiving the item. Be sure to include photos whenever possible, as these are often required to file a freight claim on your behalf. If the item was shipped to a terminal, it must be picked up within 48 hours or a $45/day storage fee will apply.
We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.
To be eligible for a return, your item must be in the same condition that you received it, unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. Shipping costs back to Canadian Off Grid are the responsibility of the customer and 15% restocking fee will apply.
To start a return, you can contact us atryan@canadianoffgriddepot.com. If your return is accepted, we’ll contact you to discuss options, as well as instructions on how and where to return your item. Items sent back to us without first requesting a return will not be accepted.
