Gen charge battery storage for car garage

[cball]

Yo! Looking at powering a 30x90 metal bldg with a generator only to use for lights and car lift when at the location, BUT this project needs to have a battery component on the power side to allow use of security cameras. What I envision but do not know the correct combination of gear to accomplish is as follows:
- 12kw auto start gen w\ modern options for wifi connection & scheduled runs.
- 120\240v capable inverter charger that can handle max load of 240v hydraulic pump on car lift (15a rated would like to know system could catch a 20a peak)
a. Inverter should have ability to detect state of charge and call for generator "run" to recharge battery
b. inverter should be able to be remote accessed via app
- 48v LiFE battery that can handle lift load.
a. lighting and camera load is low. Lighting is 46w x 19, cams are 30w x 2. If these are full tilt it's an 8a draw on the 120v
b. Figuring 5-10 lift uses annually.
- capable of installing solar at later date if desired.

What I don't know is how to find an inverter that will configure to my "run" call need or options to get that result. Also, I don't know what equipment outside of the more expensive stuff I've used in the past (sol-ark, kilovault, qcells) that could do this job on a budget.

Adding some color here because I went all bullet pointy (first post) and now I regret it...oh well!

Something like an affordable rack battery or pair of batteries and a victron charger\controller\inverter is what I had in my mind. I've never used victron, but the need to monitor battery level and call for recharge from the generator sounds like something a victron would or could do. I'm well out of my depth on this but looking for suggestions on what gear to put together to make a decent system.

Big thing to keep in mind is that most of the system draw will be very low. Security cameras only, and\or camera and security lights as needed based on motion. Only on a weekly or biweekly basis for lights to be added and only 1x per month max for the lift. Likely much lower actual use on lift.

CcGX and Venus GX the only option that can use state of charge as basis to call for generator run? I think the quattro series inverters may be a good fit & the PDF you linked says that quattro has a virtual switch that is configurable. @MisterSandals - where would you buy your victron gear if using in SE USA? I'm asking more for support related side, but cost is important too

I was thinking Amazon but don't see it there.

The surge to run the lift is going to require a fairly large inverter, but your overall power usage is going to be pretty low. That surge is probably also going to drive your battery sizing because that surge has to come from the batteries. But with low energy usage you're not going to need a lot of panels to recharge.

I'll take a stab that you're going to need at least 200 Ah of 48v batteries and a 6kW inverter (actually probably a bigger inverter, like 12 kW and 300 Ah of batteries), but only 1 kW of panels. I would lean towards a 3 kW AIO with a 12 kW inverter that only gets turned on when you're going to be using the hoist, as otherwise it's idle draw is going to eat too much energy.
