The data refresh rate is the same as the Sunsynk app and yes, it's not high speed but I guess that's the tradeoff for a free cloud-based monitoring platform.
As for the generator integration, I did a test earlier with a small 3.5kw generator with a variable throttle (left on for these tests) which worked without issue. Note that I'm using app v4.05 and my inverter firmware is v0501 for the DSP and HMI is v0901 seen when connecting locally. If your firmware is older, I'd probably contact Solis support to update it.
Here are the settings I used to test the gen (connected locally via Bluetooth):
 
Main things I noticed are:
- The inverter behaves essentially like a Sunsynk inverter - it will switch all the loads and battery charging onto the generator so make sure the generator is large enough to handle what you have configure plus some loads (or turn all the loads off 😀).
- If the loads are larger than the GEN rated power setting, the inverter will not attempt to connect the generator.
With regards to the settings:
- I presume the voltage droop enforces a minimum voltage on the gen input - if it drops below this value, the inverter will not engage the generator or will disconnect it.
- AC Coupling should be off - strange that the app allows you to enable this along with the With Generator setting but it should be off.
- Couldn't figure out what Min input power does - thought it might relate to the minimum load that has to be present before the inverter will use the generator but that didn't seem to be the case.
- Gen Max Charge power sets how much of the generator power goes to charging the batteries. This setting is very generator friendly as the inverter ramps up the load so as not to make the generator frequency drop and get disconnected.
- The GEN_Start_SOC is the level which the battery has to be below before the inverter will consider using the generator. GEN_Exit_SOC is the SoC where the inverter will disconnect/shutdown the generator.
- Gen Start/Exit Voltages are presumably used if you are just using battery voltages instead of SoC via BMS, so in most cases, these won't need to be changed.
- Gen signal would be used if you want to use the inverter contact to auto start a generator that has a controller or support for remote start signalling.
- Gen force usually forces the inverter to use the gen input, regardless of the other configured conditions. I didn't test this function but presume it's the same as the settings on a Sunsynk/Deye.
- Gen Stop on my app can't be enabled but maybe it's a toggle - perhaps one can manually force the start signal contact to open and thus stop the generator.
- Smart Load Switch - not sure how this could be enabled if With Generator or AC Coupling is enabled - seems like only one of these should be possible to enable at once.
Note, there are no frequency tolerance adjustments here. I presume the inverter uses the same frequency tolerances on the gen port as the grid settings so one might have to adjust those, especially the lower end side if the inverter switches in the generator but then tends to kick it out immediately as a load is turned on and the frequency drops too low. You can find the frequencies under Grid Code Setting ->Grid Code Parameters. I believe the ones of interest are the Startup/Recover FH/FL settings near the bottom of the list. I didn't have to adjust mine for charging the battery and turning on an inverter-type aircon, but the inverter chucked the generator off when I turned on a 1.2kw hob plate. That is often also related to the use of the dynamic throttle on the generator which sometimes isn't fast enough to respond.
It would be diagnostically useful for Solis to add some real-time details to the generator info section that shows the current generator input frequency (and voltage, if it's not there, can't recall now as it doesn't show up if the generator is not connected).
Here's a screenshot of the power flow with the generator working:

Powerforum store is awesome, and proper advice available if needed.
Just got my Solis, panels and batteries from the guys. 

That's so sad, sounds like you are fortunate to be alive, and this from trusted personal referrals. I hope that your folks and brother have had their systems reviewed too.
I hope that forumites will benefit from your experience, and use it to properly vet potential installers. It's not good enough to just get a word of mouth referral from a layperson, I would strongly suggest that people actually do physical visits of reference sites, inspect everything and ask to see the paperwork, before committing a deposit.
