An installation I did a few months ago has developed a problem which I’m hoping someone here might have a solution to.
The firmware in all components of the ES-II were updated to current prior to installation.
WiFi is via hotspot on the customer’s mobile phone which he takes off-site frequently, but also places in range (close proximity) of the ES-II to allow data to be uploaded to VRM at least daily.
For the approximately two months from installation it all ran smoothly, but now the WiFi in the GX device is not connecting to the phone.
When I went onsite it appeared the unit had ‘lost’ the WiFi password.
After re-entering the password the unit displayed ‘Connecting’ for a few minutes (maybe 5-min?) then after logging on, lost that connection almost immediately.
I repeated the logon attempt using a different phone (mine) and saw the same thing.
Back to the customer’s phone and it happened again.
Is it possible there’s a fault with the unit, or is it likely to be a programming issue, or something in the recent firmware?
Along with the EasySolar-II, the system comprises 12 x 285W PV, 3 x PowerPlus Lithium Cells (in parallel)
Any advice or information greatly appreciated.
