Boat hydrogenerator 7105_7111

for sailboats

Overview
The Hydro Charger Universal is a hydro generator for sailing vessels, designed to produce electrical energy while underway. Compact and lightweight (approx. 8 kg), it is suitable for coastal and offshore use and can generate power from speeds of about 3 knots thanks to a specially tuned propeller.

Real‑world test
Measured during a day’s sailing: with a refrigerator (4 A) and autopilot (6 A) running continuously, battery state rose from 75% at departure to 82.2% after 7.5 hours of sailing.

Key features

• Construction: 316 stainless steel, delivered fully assembled (boat mount excluded).
• Weight and size: approx. 8 kg; product dimensions referenced without propeller 90 x 28 x 8 cm; installation reference 110 x 10 x 30 cm.
• Low‑speed generation: tuned propeller allows charging from ≈3 knots.
• Adjustable charging current: up to 20 A (12 V).
• Programmable final charge voltage: 13.8–15.0 V in 0.1 V steps.
• Plug‑and‑play operation: hang in the water and generate while sailing.
• Controller included: Powerbox electronics, 12 V regulator controllable via Android app (Bluetooth).
• Controller consumption: 30–40 mA (depends on display brightness), 0 mA when turned off.

Mounting options

• Fixed stern mount (use only when vessel is stationary).
• Swing/pendulum bracket with side stops and up to 180° pivot.
• Detachable angled mount for swim platform.
