Greengoods4U are pleased to offer this exceptional 350W 12V solar charge controller which boasts a unique combination of both MPPT and Dual Battery functions. This best-selling model is the very first of its kind; combining two highly sought-after features to create a previously unprecedented type of solar charge controller. German design, engineering and manufacturing also ensure unrivalled quality and reliability.
Dual Battery Capability:
This high quality 350W 12V dual battery solar charge controller is designed to charge and protect 2 batteries simultaneously, with automatic cut off to prevent over-charging. This makes it a perfect solar controller for a caravan, motorhome, boat or any other system with 2 batteries (e.g. engine and leisure battery). The main battery will be charged with full available power, whilst the second battery will be trickle charged (max 1 Amp). Please note: this controller also functions with only one battery connected. In this case, 100% of the charging current will be passed to the single battery. A second battery may be added at any time.
Maximum Power Point Tracking (MPPT) Technology:
Using the most advanced technology in the solar controller market, this controller specifically pinpoints the maximum power voltage point of the solar panel(s) as it varies depending on sunlight exposure and temperature. This ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range - this controller can work not only with standard off-grid solar panels, but also with on-grid panels or solar panel arrays up to 50V. The maximum allowed input solar power for this controller is 350W.
Full Range of Protection Functions:
This charge controller features a comprehensive set of electronic protection functions to prevent reverse current at night (from the battery back to the solar panel), over-charging, short circuit and battery reverse polarity protection.
Advanced Battery Compatibility:
Unlike many other less advanced solar charge controllers, this model is 100% compatible with a broad range of battery types, such as Gel, AGM, Lead-Acid Flooded and Lithium batteries; with several different charging options available for each type.
Additional Special Features:
This 350W 12V solar charge controller also has connection sockets for a remote meter and AES-enabled fridges (Automatic Energy Selector e.g. in some Dometic/Electrolux fridges). When the battery is full, this controller will automatically divert any excess solar energy to the AES fridge; thereby switching the fridge from gas/mains to 12V operation.
The built-in fan for cooling makes its design compact and lightweight. Whilst other controllers require heavy passive metal cooling systems, this model is protected from overheating, whilst remaining aesthetically and ergonomically pleasing.
