Sterling Power PCU2430 Pro Charge Ultra 24V 30A Marine Battery Charger

Sterling Power PCU2430 — Pro Charge Ultra 24V / 30A Marine Battery Charger

The Sterling Power PCU2430 is a marine-grade AC battery charger built for 24V systems requiring fast, reliable shore power charging across up to three battery banks simultaneously. At 30A output on a 24V system — equivalent to 720W — it delivers a solid charge rate for medium to large 24V house banks and is a natural fit for sailboats, powerboats, and commercial vessels with conventional 24V electrical systems.

The Pro Charge Ultra platform has been refined over years of real-world marine use and won the innovation award at IBEX 2010. It runs on any global AC power source between 80–270V and uses Power Factor Correction (PFC) technology to reduce input current draw, generate less heat, and minimize electrical noise. A full 4-stage charge profile — bulk, absorption, float, and equalization — is applied automatically, with multiple battery type profiles including support for AGM, gel, flooded lead acid, and lithium. A battery temperature sensor is included for voltage compensation and thermal protection.

The PCU2430 is conformal coated for salt air and humidity, conforms to the ABYC drip test when mounted correctly, and uses non-ferrous metals throughout. Optional remote control (PCUR) available separately.
