Its hard for me to
answer this question without context.
What type of tools do you need the electricity to power?
How much power does it use, normally and at peak/startup?
How long do you need to power the tools for on average?
What size gas-generator would you have bought to do these chores?
The average household outlet provides 2000W, so maybe you just want something that does that, and you want it to sustain 4hrs of "chores".
It might also help to think of it in a similar light as battery powered tools, that you charge with the grid, then bring it with you to do "chores"
So what if you had a 2000W solar array+charger, with 4hrs worth of battery+inverter, and then you could just disconnect the battery pack and bring it with you to power your tools for the chores.
Alot of times it can be hard to get a shade free place next to the worksite for solar to really work and even harder for the low angle sun to "juice up" the tools in the early morning or later afternoon.
But to give your question a short answer, this is the system that I would recommend:
2000W of solar array (with about 4hrs of sunlight) for $2,000
2000W charge controller (48V x 50A) for $500
8000WHr of LiFePO4 Battery (48V x 200AHr) for $6000
2000W inverter with a peak of 6000W for $2000
