Proper charge controller amperage in Renegy 800 W kit?

[schiesserm]

I was recently reviewing Renegy's 800 W 12 V kit, it says :

What Is Included in the 800W Solar Panel Kit?​

The 800W solar panel kit comes with many of the same materials as the 400W solar panel kits, such as the mounting Z brackets, solar Y branch connectors, and 20-foot 10 AWG AK. Additionally, the 800W solar panel kit comes with a total of eight 100W panels, a Rover Li 40A MPPT charge controller, two-foot 8 AWG fuse cable, eight-foot 8 AWG tray cable, 20A in-line fuse, and 40A ANL fuse, and a BT-1 Bluetooth module.

Seems like 8 100W panels in a 12v system should need a charge controller rated for higher wattage or 800/12=66 amps. WHat do you guys think. got it off this page:https://www.renogy.com/blog/differe...any Batteries Do I,just need that one battery.

40a is sufficient IMO, very unlikely to yield 100% of rated pv size unless you are very lucky.

Current connected sell an 800W kit, they use a Victron 150/60 60A charge controller which can actually deliver the full 800W theoretical:

12V/24V 800W Solar Panel Kit | Current Connected

Embrace solar power with our 800W Solar Panel Kit for small RVs, boats, and vans. Efficient, versatile, and LiFePO4 compatible.

Well worth the difference in price IMO to go with the Current Connected option

Edit to add:

Versus this:

800W 12V/24V Monocrystalline Solar Premium Kit w/Rover 60A Charger Controller

This Premium Kit is perfect for installation on an RV, boat, or camper. It can also be installed in a ground mount system next to an off-grid campsite, making it an ideal choice for many off-grid applications.

Hmm the Renogy 800W kit also has a 60A controller?
