Product Description

Portable Pure Sine Wave Power

The CPS400ESA12 delivers clean 400W pure sine wave power from a 12V battery in an ultra-compact aluminum enclosure weighing just 3.12 kg. For camping, RV, marine, and small off-grid applications where space and weight matter, this inverter provides reliable AC power without compromise.

Smart Power Management

Automatic transfer between battery and AC input (utility or generator) ensures power continuity. The idle power saving feature reduces consumption when no load is connected, preserving precious battery capacity. Surge handling up to 800W for 0.5 seconds accommodates motor startup loads.

Built Tough

Aluminum construction, wide operating temperature (-20°C to 50°C), and overload protection ensure reliable operation in harsh environments — from desert heat to mountain cold.
