How to Set Up Solar and Battery Banks in 7D2D

​

Powering Your Defenses

To survive the Blood Moon, you need active defenses like Blade Traps and Turrets. These require a consistent power source to function during combat.

​

Power Sources

1. Generator Bank:
   • Converts Gasoline into electricity.
   • Produces significant noise and heat, which can attract Screamer zombies.
2. Battery Bank:
   • Silent operation. Requires lead-acid batteries.
   • Can be charged by connecting it to a Generator or Solar Bank.
3. Solar Bank:
   • Silent, infinite power during daylight hours.
   • Note: These cannot be crafted; they must be found in high-tier loot or purchased from Traders.

The Wire Tool & Grid Setup

1. Wiring: Equip the Wire Tool. Right-click the power source, then right-click your switch or relay, and finally right-click the trap.
2. Range: Wires have a maximum reach of 15 meters. Use Electric Relays to extend your grid across larger bases.
3. Wattage: Every source has a limit (e.g., a full Solar Bank outputs 180W). If your traps draw more than the output, the entire grid will shut down.
