Hi, 

Are there any decent 3kw inverters out there have the following criteria? Ideally im looking for an inverter than supplements Eskom during the day, with some battery backup for loadshedding.

Ideally I am looking for the following:

• Wifi or 4g capability for remote monintoring. (its a rental propert and we want to monitor from home for errors etc)
• Able to mix solar and grid to the house - ie, excess solar is used to supplement eskom
• Able to tie directly into all circuits on the DB, and when loads exceed 3kw for longish periods, the inverter handles it and perhaps bypass it to the grid

Does something like this exists?

There would be a gas stove, Led lights through, solar geyser. 

Battery we are looking at is a 2.5kw hubble or similar.

Do you want to just monitor remotely, or do you want to be able to configure it as well?

Remote monitoring is not a biggy, plenty of inverters will give you that. Mixing solar into the grid is also, I think, not that uncommon a requirement. My Goodwe does that, and it's not the only brand that does. Since you are going light on batteries (just enough to get through a load shed), you should have plenty to blend with the grid supply. There may be issues with some municipal meters (which I can't advise on), but maybe ask questions about that, especially if you are going to export any spare capacity in order to maximise savings (also check the tariff tables and see if there will be saving. Here in Johannesburg, running off of City Power, I can't see how there's a saving for me if I export). 

I think it's your last point  that narrows the field down. My Goodwe can't do that, though I can't say I've often found myself longing for such a facility. We have a split DB - backed up and not backed up loads - and the ability to feed both sides of the DB when there's sun and when there's grid takes care of most eventualities.
