### 5/5 — Great remote monitoring and control

*2026-06-29, version 1.6.6*

Have had 2 systems with 6 pro batteries on one, and 3 on the other for 2 years. Can monitor, or adjust remotely, if needed with ease. Great systems.

### 4/5 — watch enabled

*2026-03-11, version 1.6.6*

would be nice to have baoc info on watch chrg percent swipe up power out Swipe up pv power etc. big numbers easy to see

### 3/5 — Good hardware, godawful software

*2026-02-19, version 1.6.6*

I have had so many problems setting up this inverter. All because of “lowest bidder” software and bad documentation. When I finally had it connected to the cloud I come to find out this app is absolutely atrocious. The web portal is marginally better but even that was written by amateurs.

### 1/5 — This app is garbage

*2026-01-16, version 1.6.6*

This app is full of spyware and it literally refuses to work unless you enable location tracking. Do not use

### 2/5 — Location Access Required, Overly Constraining

*2025-11-11, version 1.6.5*

It seems that a recent update makes the app now require location access to launch the "local connect" option for monitoring/interfacing with the inverter. This may be a bug, or intentional, but either way it's not acceptable.

### 5/5 — Don’t stop

*2025-11-05, version 1.6.5*

Need to incorporate the same functions on the web version. One is the lack of import grid metrics, to compare to the export numbers.

### 1/5 — Gridboss and ac coupled solar

*2025-10-25, version 1.6.5*

EG4 hardware is fine, but they need help with software. App is really bad. AC coupled solar doesn’t show as solar in app. App is super slow and non responsive. Programming settings is a mess. They need to realize they need to higher experienced software people in US.

### 5/5 — Good but could use improvement

*2025-10-25, version 1.6.5*

I like the function of the app.  The only improvements are a better history and make the numbers a little larger for us who have trouble seeing the numbers on the app.

### 3/5 — Dark mode

*2025-10-22, version 1.6.5*

Please give us dark mode it’s too bright

### 3/5 — Consumption

*2025-09-27, version 1.5.9*

Why does the consumption not show on the app? Our equipment isn’t on WiFi but when I check the app when in range the consumption always shoes zero.
