EG4® MPPT100-48HV - Your Ultimate Solar Charge Controller Solution
The EG4 MPPT100-48HV is a cutting-edge solar charge controller, designed to revolutionize your solar energy system with its Maximum Power Point Tracking (MPPT) technology. Drawing inspiration from the EG4 3kW All-in-One Solar Inverter, this simple, affordable, and reliable controller ensures you extract the maximum available power from your PV modules.
EG4 MPPT100-48HV Solar Charge Controller Highlights
- Maximum Power Extraction: The EG4 MPPT100-48HV efficiently converts the higher voltage from your PV modules to the optimal lower voltage for charging your battery bank, maximizing solar harvesting capabilities.
- Impressive PV Array MPPT Voltage Range: No need for combiner boxes, with a max open-circuit voltage of 500VDC and a 5500W max usable solar panel PV array power.
- High Charging Current: Enjoy a 100A max charging current for quick battery charging rates, adjustable from 0A-100A (default 80A), capable of charging a 5.12kWh EG4 battery in approximately 1 hour at 100A.
- Battery Compatibility: Works with a 48V nominal battery voltage, and a 48-62VDC charging voltage (default 56VDC), ensuring optimal performance for your energy storage system.
- Built-in Safety Features: Includes built-in breakers for added protection, such as a PV array DC disconnect breaker and a built-in battery breaker.
- Efficiency and Performance: Boasts a 94% max charge controller efficiency with less than 25W self-consumption.
- BMS Communication: Capable of communicating with EG4 batteries through its RS485 BMS port, even when operating with non-EG4 compatible inverters.
What is an MPPT Charge Controller?
An MPPT, or Maximum Power Point Tracker, is a DC-to-DC converter that optimizes the power transfer between your solar panel array and the battery bank. It converts a higher voltage DC output from solar panels down to the consistent voltage needed to charge batteries effectively.
Key Features
- Optimized Solar Harvesting: Ensures maximum power extraction from your solar panels.
- Advanced Protection: Includes built-in breakers to safeguard your system.
- High Efficiency: Delivers 94% max efficiency, outperforming similar-sized competitors.
- Versatile Compatibility: Suitable for various battery types and solar power systems.
- Easy Integration: Simple installation process with advanced monitoring capabilities.

I almost NEVER leave a 5 star review. They are reserved in my world for places that do something EXCEPTIONAL. Kyle A. And the crew at Cabin Depot are a group of those exceptional people. They patiently worked with us as we developed our off grid setup and provided not only fair prices, but wonderful follow-up with my installation and operational questions as our system came together. Thank you and we look forward to a continued relationship.
I purchased a drolet myriad III wood stove from cabin depot. Customer service was great, delivery was fast and they replied to all of my questions very quickly. When I received the wood stove I unboxed it while the driver was here (as suggested by the company). Everything was perfect and the driver from midland transportation was very accommodating.
A+ thank you very much!
I’ve taught customer service to many organizations in my professional career. I’m now long retired and still find excellent customer service difficult to come by!
The Cabin Depot, and especially Kyle Aubin, are exceptional examples of customer support and service!! My only regret was not reaching out sooner!
I would have saved myself significant time, lessened aggravation, and a happier installation of my EG46000XP and generator backup.
Lyle’s patience and response time, his pleasantness and professionalism, will contribute significantly to me looking first to them for future sales and service!
We ordered our PV panel, battery bank and inverter set up in September 2024. There were a number of hurdles to get over and many times we worried we were not going to accomplish our dream of greater self sufficiency.
With the owner of Cabin Depot involved, we have received strong support in resolving our issues and have now got an inverter, lithium battery and PV set up which has taken us from using a generator and having periodic power, to uninterrupted power supply allowing us to run a number of electrical devices continuously, including our well pump and a modem.
We look forward to a continued relationship with Cabin Depot and thank them for helping us to get over the finish line with what has been a daunting project.
Recently added a EG4 LL battery to my existing system.
Cabin Depot was great to deal with, shipping was around a week., which is pretty good considering it was shipped across Canada.
Only delayed by 1 day but that was a UPS thing.
This battery was added to 3 existing EG4 Lifepower batteries.
Everything worked no issues at all., only thing was the communication ports are in different locations and the supplied cables are too short to reach,
No big deal.
All in all very happy and would order again
Propane stove came on time in perfect condition, super easy install, helpful customer service, very competitive price!! Just a good company. We will be buying more off grid supplies from this fantastic group of professionals!!
I was so impressed last year when I called from Alberta - searching for the right equipment (hot water on demand and propane heater… and I have to say I am impressed again - today was just a special order thermocouple to have as a spare - the service you provided for a 35 dollar part was above and beyond.
