My approach to solve this achievement was to create a mobile power convoy setup.
For Sylva, Desolo & Calidor useI built a large shuttle and stocked it with:1 tractor
1 medium rover
2 medium battery
1 small solar panel
1 small wind turbine
5 small batteries
1 medium storage
2+ packagers or graphite
This setup allows for a user to fly above the planet and monitor for landing spots near gateways that have yet to be opened. You can pack more for the trip to help out if you package everything into its smallest forms. Note: Be aware of your rocket fuel levels during all this. Various planets will increasingly require more power generators or batteries to reach required power input. Check table listed at bottom of guide.
Land, unpack all the gear and set out to travel w/ the convoy setup. Place a small solar panel and small wind turbine on the front of your tractor as it should keep the vehicle powered all the time. Have the medium batteries unpacked on the medium rover so they charge while in transit. Once you reach a gateway plug the convoy in from the back end of the rover. When I needed extra power I would search the surrounding area for compound to create small generators and then organics for fuel.
Power Generation Output:https://astroneer.gamepedia.com/PowerMedium Battery = 3A
Small Battery = 1A
Small Generator = 1A
Medium Rover = 1A
Small Wind Turbine = .5A
Small Solar Panel = .5A
With the equipment brought we can generate
2 med Battery = 6A
5 sml Battery = 5A
1 med Rover = 1A
----------------------------
12A
Once a gateway is solved, you can continue to roam the surface for more. Following the grid lines of the linked portals for fastest route. Otherwise, drive back to the shuttle, use the packager to pack up items and strap the shuttle for another launch and look in the sky to see where to land next.
This setup will work on every planet, however you will have to adjust for power requirements. You can use large rovers to carry more but they are slow moving and cumbersome on rough terrain. You will have to adjust the caravan load to accommodate the power requirements for each planet gateway listed below. Novus, Glacio, & Atrox require an atrocious amount of power.
I recommend use of the RTG if you can have it made.
RTG = 4A
This is the highest power output device in game currently
Here is a chart from the Astroneer wikihttps://astroneer.gamepedia.com/Gateway_ChamberPlanet | Chambers | Amps Required
Sylva | 6 chambers | 5A
Desolo | 2 chambers| 8A
Calidor | 6 chambers | 12A
Vesania | 6 chambers | 16A
Novus | 2 chambers | 21A
Glacio | 6 chambers | 26A
Atrox | 6 chambers | 30 A
