The controller converts the solar pv voltage down to the battery charge voltage, and at the same time the current is boosted. Victron MPPT 75/10, 10A 12/24VDC Solar Charge Controller Victron’s 75/10 charge controller offers a high specification, current boosting MPPT controller in a compact, marinised package. WindyNation’s TrakMax 30L utilizes a state of the art maximum power point tracking (MPPT) software algorithm to maximize solar panel power production. An Introduction to Victron MPPT Solar Charge Controllers Victron have been making marine electronics for over 35 years and have earned a worldwide reputation for reliable products.
WindyNation TrakMax 30L MPPT Solar Charge Controller with Digital Readout and User Adjustable Settings Compatible with (1) AGM Sealed Lead Acid, (2) Deep Cycle Wet Lead Acid, (3) Gel Cell and (4) Lithium batteries Compatible with 12V, 24V, and 48V batteries. The controller features an ultra-fast MPPT tracking algorithm and intelligent battery management to maximise battery life. The electronics of the 75/10 unit are fully encapsulated to minimise the corrosive effects of damp salty air. The Victron MPPT solar pv controllers are released under the ‘BlueSolar’ name. An MPPT controller allows high voltage solar pv arrays to charge lower voltage batteries, such as a 12V or 24V battery bank. The MPPT current boost alone can provide up to 40% more power than a standard non-mppt controller. With the TrakMax 30L, up to 98.5% of a solar panel’s power production can be transferred to the battery bank.
The end result is that the TrakMax 30L can increase solar power battery charging by up to 35% compared to conventional pulse width modulated (PWM) charge controllers! The electronics of the 75/15 unit are fully encapsulated to minimise the corrosive effects of damp salty air. The electronics of the 100/15 unit are fully encapsulated to minimise the corrosive effects of damp salty air.
