### 1/5 — Terrible

*2023-11-13, version 5.1.6*

All of the 5 star reviews came within 3 days of each other. This company has trolled the internet and posted fake glowing reviews. Do not buy this crap!

### 1/5 — Legion Solar 7 - LOL 😆

*2022-12-06, version 5.1.6*

How about you fix the app that hasn’t worked properly for over a year before releasing a new wave of products?

Another release, and still no fix. Historical data is still having issues in the newest version, 5.1.6. Other than system setup, the whole point of the app is to be able to monitor and review system data, right? Cannot review previous day(s), previous month(s), or previous year(s).

### 1/5 — Terrible

*2022-04-27, version 5.1.6*

All of the 5 star reviews came within 3 days of each other.  This company has trolled the internet and posted fake glowing reviews.  Do not buy this crap!

### 2/5 — Solar System

*2022-03-22, version 5.1.6*

Lots of frustration and trips to the roof to check on the panels and or replace the inverters or battery commanders. Very slow responding customer support. I was able to save $400 last year using 3kw system with the lead-acid battery system. Hopefully this year will be better with the lithium batteries.
The up is still unreliable. The system past performance still not available on this app. The next app version is supposed to have a fix of this issue.

### 1/5 — Inverters fail

*2022-02-16, version 5.1.6*

The micro-inverters fail customer service is a joke, the app is weak and buggy

### 1/5 — Garbage

*2021-09-14, version 5.1.3*

This system is complete garbage.  My system has constant problems.  Nothing will connect or stay connected.  The range they claim this has is not even close.  Not to mention that Im pretty sure you won’t be able to sell your house with this installed.  You can’t just put solar panels on your house legally no matter what they say.

### 5/5 — Great experience

*2021-06-08, version 5.1.2*

With the latest update the experience has been greatly improved. Very happy with the ease of adding the new sets I received from the latest indiegogo.

### 5/5 — Save money and have fun.

*2021-06-08, version 5.1.2*

Very informative system, its fun to see the solar energy production and also you’re saving the money. I like the layout its very clean and neat, the information is in real time so i can see the production rate and consumption rate right away. Very smart application.

### 5/5 — Useful application

*2021-06-07, version 5.1.2*

I have 1 starter set. Setup was a breeze, calibration proceess was a litle tricky but simple. I like how you can see all the information displayed and formatted clearly. I will get more expansion sets soon!

### 5/5 — Great app for solar data monitoring

*2021-06-07, version 5.1.2*

Just got a starter set with 2 expansion sets, I now produce free energy. This app allows me to monitor power I am producing, when the power production is highest and the money I am saving in electricity bills. Pretty cool.
