Got this exact unit for $309 on Amazon a month or two ago. Haven't installed yet but looks to be good quality!

Have you got any quotes on installation? I'm worried about the cost would be much more than the ac itself

I spoke to a few who refused to install it since it was not a brand they regularly worked with and could not guarantee warranties. For sure install will be more expensive. I eventually watched YouTube videos and learned to do it myself. Materials I needed were already more expensive than this product. Breaker, wire (outdoor rated THHN), conduit, Lbs, connectors, disconnect box, lineset hider kit, mounting bracket. There were some other additional one time costs too: vacuum pump, torque wrench, hole saws, conduit bender, step up bit.

I have since installed a couple dozen of these for myself, family, and friends. Fairly DIY friendly if you get the right tools.

Does this model have any kind of power limiter that caps the amount of power the unit can draw?

I installed one EG4 mini split in my primary bedroom and connected it to an Ecoflow Delta 2 Max using off-grid solar panels to charge. The model from EG4 has an AC limiter, which has allowed me to limit the power draw (usually 25%) and have the battery last all night.

Planning on installing another mini split in my detached garage, also with an Ecoflow/solar, but would prefer to not spend another $1,500+ on an EG4.

I'm in South Florida where you can get these things installed under the table for $300 or less. I'm pretty handy and will be installing it myself. YouTube has lots of videos on the most important - getting the line set charged. Your local auto zone or auto parts store lends them out.

Look up a company called Windsanity. They are based out of Texas but should have franchises throughout the country. I lucked out and found them and got a yitahome mini split installed in my garage for $800 out-the-door, including line set covers they provided. I was extremely happy with their quality of work and responsiveness.
