Buying notes for 4.2v power supplies
- One 300W supply carries roughly 6–8 m² of P4 outdoor module at 60% average load. Do not size by peak wattage printed on the module datasheet.
- Potted supplies run cooler in humid climates but cannot be repaired. For coastal sites, potted; for inland, serviceable is fine.
- Keep the AC feed balanced across phases. A wall pulling 60A on one leg trips breakers that the total load says should be fine.
