Inverter suggestions based on criteria / constraints

(Arizona, USA)

Hello,

I’ve been researching my tentative DIY (with electrician installation at panel) path for solar and am hoping to be advised (or humbled with insight as to the stupidity of my plan)

Long-term plan:

• 2p x 8s 320W 24V panels
• Grid-Tie (supplementary for whatever PV cannot make up; little interest in sell-back)
• Optional Batteryless Off-grid (for rare outages – Does not need to fully offset home demands)

Short-term:

I’d like to grow into my solar system, if that makes sense. What I mean is an inverter with a wide PV input voltage range that allows me to begin with somewhere around 4-6 24V panels and invest in further panels over time.

Further questions:

• Apart reintroducing batteries, how viable / common are capacitor banks to offset surges / inductive loads?

• Anti-Islanding: Is it common or not that such hybrid inverters incorporate an automatic grid-disconnect when switching to off-grid mode? Or is this an entirely separate component from the inverter system? Do most hybrid inverters simply turn off and wait for a manual disconnect from the grid before restarting in off-grid mode?

• My home is single/split-phase 120/240. For an inverter, should I be looking specifically for 120VAC output or 240?

Thus inverter requirements:

• ~5kW System
• Hybrid Off-grid / Grid-Tie
• Batteryless operation in both On / Off-grid modes
• Wide Input voltage range
• >20A PV Current (or dual input?)
• Anti-Islanding Compliant.
• High ambient temperature operation + IP64 or 65 rating

Now I’ve done a decent bit of looking around at inverters, but on account of either my criteria not making sense or my vernacular not right in my searching, I haven’t really been able to find an inverter that lists these.

I appreciate any direction, thank you.
