Samlex EVO-4248SP
NEW! Split phase pure sine wave inverter, adaptive battery charger, and transfer relay – ALL in ONE device. Samlex EVOLUTION™ Series Inverter / Chargers provide reliable AC power wherever it’s needed.
This 4200 watt, 120V /240V split phase inverter/charger connects into a standard electrical household panel. When you combine it with a 48V battery bank and a solar system you can run a fully equipped off-grid cabin, a remote mobile construction site, or use it as an emergency backup system.
Intelligently integrates a 60 Amp, 4-stage Battery Charger and a 40 Amp Transfer Relay into an advanced and affordable off-grid power solution. For use with Lead Acid or Lithium-ion batteries.
Optional EVO-RC-PLUS remote control for ease of programming and monitoring.
3 Year Limited Warranty
Features
120 / 240 VAC Split Phase (Dual Phase)
- Split phase inverter connects into the standard household panel to provide both 120 and 240 VAC output power
AC Input
- One AC input for grid or for generator, no need to reconfigure when different power source is available.
- AC input is programmable for voltage and frequency. User determines what the min and max thresholds are to switch from Grid or Generator to Inverter.
- Generator start can be initiated by “Status Relay” contact, can be programmed to activate when grid is lost.
Solar Input
- Connect a 48V MPPT solar charge controller directly to the EVOTM through the 100 Amp Battery Charger external DC Input, seamlessly integrates solar charging into the EVO’s power system.
- ONLINE Mode can be used to prioritize Batteries/Inverter over the grid, ideal for those wishing to operate primarily on solar power (when the grid is available but costly).
Battery Charger
- 3 or 4 stage charging with Equalization (must be manually initiated).
- Adaptive algorithm is used during Bulk to assess the condition of lead-acid batteries. Subsequent stages are then based on the condition of the battery rather than pre-set time periods for Absorption and Float. Prevents unnecessary charging, extends the life of batteries.
- Programmable – set battery voltage thresholds to initiate charging. Specific programmable settings for Lithium-ion batteries.
Transfer Switch
- Zero transfer time when switching from Inverter to Grid. When grid comes on, the inverter synchronizes with the wave form and then transfers instantly at zero crossing.
- <16ms transfer when going from Grid to Inverter. When grid is lost, the transfer relay switches to inverter at the correct place in the wave form for no power disruption.
Surge Capacity (Power Boost)
- 3X surge power for high surge loads on start-up, such as compressor or refrigerator
- Additionally, the EVOTM has power overload allowances available for short periods of time. Overload allowances decrease with length of time. Increased inverter capacity, or “Active Power Boost,” means you can size your inverter smaller to handle heavy surge loads, reducing costs.
State-of-the-Art Technology
- The EVOTM operates at 165 million instructions per second producing lightning fast load and response times
- The EVOTM is practically indestructible. It has “Bullet-Proof Intelligence” in the form of 9 physical points of protection monitoring being scanned up to 10,000 times per second for adverse conditions. The EVOTM will detect fault conditions and initiate a healthy shutdown before any product damage can be done.
- The EVO-RC-PLUS remote control (sold separately) can be used to capture detailed EVOTM performance data. Records all detected faults and the conditions leading up to them. Data is stored on a removable 32GB SD Card (in the remote). Use data to analyze trends for more efficient use of system resources
- The EVOTM uses five temperature sensors placed throughout the unit to determine operation of 2 speed controlled cooling fans. Reduces unnecessary fan noise and energy consumption by only running when and where the fans are needed.

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!
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.
