Kind of misleading

I want to warn anyone considering this mini split, especially from a solar website, that despite all the marketing and links suggesting it connects directly to solar panels, this particular unit does not support solar panels. The description and images, along with customer reviews showing solar setups, made it seem like a solar-ready product. However, upon purchase, I discovered it does not have the capability to connect directly to solar panels. The difference between this unit and solar-compatible models? One word in the product listing—a distinction that is incredibly easy to miss, especially when marketed on a solar-specific website. When I reached out to customer service, they acknowledged that this confusion happens frequently. I even requested they update their website to make this clearer, as it’s misleading and easily misinterpreted. While the customer service team was polite and professional (something I truly appreciated), the resolution offered was disappointing. They provided free shipping on an inverter (an additional cost to me) or free shipping on a different unit. While better than nothing, these options fail to address the core issue: the misleading marketing and how it caused me—and apparently many others—to purchase the wrong product. For context, I spent roughly $1,700, including taxes and shipping, on this unit. Now, I am unable to power it without running electricity to my barn, which could cost $4,000–$5,000. Had the website been clearer, I would have never purchased this unit. Worse, because the unit has been installed and the packaging opened, I am now unable to return it. As a business owner myself, I find it unacceptable that the company has not taken steps to fix their website to prevent further confusion. Even after I pointed out the issue, they chose not to act. If this has happened “quite often,” as they admitted, why not make the necessary adjustments to save future customers the hassle and expense? I appreciate the politeness of their team, but polite customer service does not make up for poor business practices. In situations where there is a clear miscommunication due to the company’s advertising, the right thing to do would have been to replace the unit or offer a partial refund. At the very least, they should fix the website to prevent others from going through the same ordeal. This experience has left me frustrated, out of pocket, and with a unit I can’t even use unless I spend thousands more. As it stands, I am seriously considering contacting my bank to dispute the charge due to what feels like false advertising.

New mini split

The short version is , excellent product and provide as advertised. I run here a 15 k off grid operation and the efficiency is outstanding. My 2 story house get planty of cooling ore heat. I have two mini split providing plenty of comfort. Once the desired temp is a stablish the unit idle down and use about 340 to 350 watts. Real impressive and I can only recommend it for every one who wants to conserve electricity.

It's working great!

I purchased this unit and 4 410w solar panels from San Tan solar after watching the reviews for a year. Installed the mini split a few weeks ago and it's running good assisting my old house AC. I got the solar installed right before we were hitting 110 deg in Phoenix. It's working like a champ! In one week I've got over 50kwh of "free" solar air conditioning! And while I was installing the unit I had a "problem". It wouldn't turn on. After checking everything I could think of I sent an email to the company and they called me 30 minutes later! They walked me through some common mistakes installing the unit yourself and when I checked a connection I found the bug. Literally a bug! Smashed in a wire connection. This is a great mini split. It's even better because it can run on solar AND grid power! And it can balance the two at the same time when solar isn't enough. 3 weeks running this mini split and haven't had a problem. 1 week with solar and over 50kwh of solar used to cut my power bill! It's 113 today and I'm really enjoying my "free" AC!!!

If I can install it, anyone can - amazing performance!

Delivery was simple and straightforward from signature solar. The unit came well-packaged and protected adequately for shipping. We sourced some local used commercial Sunpower panels (cheap here in the Southwest) and got to work! Installation can be intimidating, but I've never touched an HVAC system in my life and was able to get the whole AC unit installed and working on grid power in a single day. Solar tie-in took a bit longer but that's not the fault of the EG4. Operation is a bit hard to figure out given parts of the manual look like they were Google Translated from Mandarin to English in sections, but there are tons of videos and forum posts online to help. Kudos to SigSolar for putting up a step-by-step installation video on YouTube! That was a big help. Running full-tilt, non-stop the unit seems to use about 20kWh per day on grid. Overall it is significantly more efficient than our central air and - as a supplementary cooling solution for the harsh summers in the desert - provides incredible utility. Once we got the solar set up and installed, our central cooling kicks on less than half us much throughout the day. Haven't seen a power bill yet, but I anticipate at least a 25% savings based on current grid usage in the summers. This thing will pay for itself in under 3 years. Haven't had it long enough to comment on longevity but it appears to be well-built and sturdy!
