Photonic Universe 20A solar charge controller / regulator 12/24V for camper / caravan / boat

Product Description

This high quality,brand new, powerful 20A 12V/24V solar charge controller is designed to protect batteries whilst charging them,with automatic cut off to prevent over-charging and deep discharge. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your battery. Often PWM technology can recover some lost battery capacity.

This controller stops reverse current at night (from the battery back to the solar panel) so your battery won't lose any charge. It has many other protection functions such as over charge / discharge, over load, short circuit, overheating etc. Other features of this controller include LED indicators, temperature sensor, and aload "on/off" button. One of the greatest benefits of this powerful 20A controller is the small size - only 16x8cm.

This controller can work with sealed, gel, and flooded batteries (the default is sealed) or a user-defined battery type (please note battery type can only be changed from default using one of the communication methods listed below).The controller canaccept up to 320W (12V battery) / 640W (24V battery)of solar power input, which makes it a perfect choice for small or medium solar PV systems with a battery and load; such as in a campervan or boat.

This model also features advanced communication technology, whichoffers the user the opportunityto monitor and program parameters for the solar charge controller through various methods:

1) The controller can be connected to a remote meter MT50 with an LCD screen, which displays system performance information and allows the user to manually adjust parameters and load settings

2) An RJ45 to USB cablecan be used to connect the controller directly to your PC / laptop, where parameters and settings can be monitored and adjusted via a free computer program - Solar Station Monitor(Windows-based PCs and laptops only).

Using one of these communication methods,the user will gain access to various charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, accumulatedcharge anddischarge energy,min/max voltage and other information.If required the user will also be abletoamend the battery type and capacity, set charging volts for different charging stages, specify the duration of each charging stage,create a user-defined battery type with charging parameters specific totheir battery (if the pre-existing options are unsuitable), personalise the 'load' settings (e.g. set timers for lighting, fans, pumps) and more.

In addition to the built-in temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor, which can be attached directly to the battery to measure the battery temperature more precisely and optimise the charging process.
