What we try to catch before recommending anything
Budget gear can be a good deal, but only when the listing is specific enough to verify. The guides here treat vague claims as a reason to slow down.
- Buying by the biggest watt-hour number before listing the loads.
- Ignoring solar input limits and assuming any 200W panel will charge at 200W.
- Trusting kit photos when the listing does not name the controller, wire gauge, or connector type.
- Treating short product blurbs as proof that a battery can run a refrigerator, pump, or tool.
