Summary of Key Differences
The two solar charge controllers share nearly identical voltage ranges, current rating, PV power limits, and battery support. POWLAND listings on different stores consistently claim 98% efficiency, include the temperature sensor + RS485 cables in the package, and stress 3-stage charging for battery life. EARNMee more frequently highlights lithium activation, metal construction with specific product dimensions/weight, adjustable current, and IP21 rating in some descriptions.
Real-world durability, long-term reliability, and exact firmware/behavior can vary by batch; both are value-oriented units rather than premium-branded controllers. Therefore, before choosing and purchasing, always verify the latest seller specifications, including proper fusing/wiring sized for 120A, and ensure adequate ventilation. Also check for verified customers reviews, ratings, and compare prices across different market stores.
