The HP-AHP20SA series inverter/charger should be installed with specific environmental considerations in mind:

Temperature and Humidity: Suitable for operating in temperatures ranging from -20°C to +50°C. Above 30°C, charging and load power may need reduction, and 100% load output is not supported. The storage temperature range is -25°C to +60°C, with relative humidity below 95% (non-condensing).

Altitude: Ideal for altitudes up to 4000 meters. Above 2000 meters, the output power needs adjustment.

Installation Environment: It is recommended to install the inverter/charger indoors, away from humid, salt spray, corrosive, greasy, flammable, explosive, or dusty environments.

Safety and Wiring: Ensure proper ventilation, particularly in enclosed spaces. Avoid placing the inverter/charger near flooded lead-acid batteries.

Make sure that all connections are tight and secure to prevent heat accumulation and potential fire hazards.

Use cables and connections appropriate for the current density, and ensure the inverter/charger is properly grounded.
