Recommend a replacement inverter

[baldelectrician]

We don't normally do PV, however I was called to a PV inverter with no power, 6 years old

Found supply OK, however fed through a AC type RCD.

PV inverter has power, no display etc, no fuses blown

Supply Zs OK, voltage at strings (about 260V in afternoom, east west split)

DC and AC isolators present, no SPD on AC or DC sides

No internet, online possibility option - does this affect choice (do some operate online only?)

What would you recommend as a 3.68kW / 4 kW replacement?

I have been happy with my Solar Edge and its online portal/app.

No of panels, wattage of panels, no of strings will also be needed to choose, you can overdrive the inverter a little, Solis have a good range for that size, some are 1 string some are 2. Internet not needed but is used for app for client to view. Setup is via inverter panel.

Hi,
There are 8 x 250W panels on each string
