Royal Jelly Harlem.From eco-conscious homeowners to self-taught underground bunker builders, anyone using a solar panel larger than small trickle systems needs some sort of battery regulation, which is where solar charge controllers come in.
The price of the controller, combined with the price of the panels and batteries, means solar system users may be intimidated by the wide range of models available on the market. With a little bit of math, a touch of research, finding and buying the best solar charge controller for your system can actually be quite simple. There are, of course, several important considerations to keep in mind, like safety features, reputation of quality and price point.
Purchasing a high-quality solar charge controller is an investment, especially for a top-of-the-line MPPT models. Each user will also need to take into consideration what type of device they want to charge, whether that be a large household with an off-the-grid system, or an RV with deep-cycle batteries.
Ironically, solar panel kits work best under cold and cloudy conditions with full sun. This is because temperature affects the efficiency of a solar panel; a watt panel at room temperature will be become an watt panel in degrees. In these cases, an MPPT controller is the best option because it regulates temperature and compensates for the change in voltage. Some solar controllers offer battery temperature sensors which will enhance the battery capacity.
This is a great option for those looking to place their panels in varied environments with strong weather patterns. Depending on the voltage of your solar panel, you might not even need a charge controller. When it comes to small panels that put out 2 watts or less for every 50 battery amp-hours, solar charge controllers are unnecessary.
However, you should equip every solar panel and battery that puts out more than this general standard with a charge controller. That will regulate the output and efficiency of your system. However, the most important part is the capacity of the controller to handle the current from your solar panel array.
The load terminal has a low voltage disconnect and will turn off a connected device to keep the battery from being expired. This option is used for non-critical loads and can sometimes be used as a lighting controller that will automatically turn the device on at dusk. However, this system is only used for very small inverters and cannot be used with anything higher than 60 amps as it may cause it to malfunction.
On the other hand, large devices, like grid solar panel systems, require an MPPT controller. These technologically advanced and expensive controllers are much more suitable for large loads. However, an MPPT solar charge controller can allow you to use a much smaller wire as it will convert the voltage. MPPT controllers are widely accepted as being the best of the best, so they inherently top our list.
Most battery charging units fall within the VDC range. However, some may need a capacity of 60V or 72V. The base standard is 12VDC, but for those running very large systems, like compounds or entire households, a higher voltage capacity is necessary.Average rating 3.

Dollars could you recommend one please??? Thank you for your comment, Kindly know that any your contact information has been removed for protecting yourself and your privacy.
The above list has been updated, We have listed the best options available, also your choice depends on what is perfect for the solar panel system you have. This list is okay but seems like it came from the star ratings off of Amazon and not personal experience. I have used all sorts and the cheap no-name ones do not last or will at some point fry your batteries.
I also use the Duracell golf cart batteries which have turned out to be a good choice. You should get a good hydrometer to help maintain your batteries and always refill with battery acid or top off with distilled water only. Your batteries will live a lot longer this way.

Solar Panel Controllers
To make a secure and watertight connection through the roof of your motorhome or the deck of your boat:. Truman — June 8, I recently purchased this product, but when I came to use it, I found there was no Amps readings.
I contacted sunworks regarding this issue and I spoke to Tony Weldon who informed me of a series of checks to perform to correct my issues. He asked me to check if there was anything blocking my solar panel, in doing so I identified my TV ariel covering a small portion of the panel, severely reducing the Amps generated and this instantaneously fixed my problem.
This unit is now working brilliant and is a very well made quality product, I would also like to recommend the professionalism and fast response from Tony.
Fan — June 30, This works well for me. Inside the unit looks to be good commercial quality and the connectors feel beefy enough for the job. In service it seems to charge the battery efficiently and keep it topped nicely. N Ball — November 17, Smudger — June 17, I struggled to justify the replacement, but looking at the new SB2C controllers specification, I thought it may just be worth upgrading to get the extra battery capacity.
The Sunworks Controller is above Controllers. The Sunworks Solar Panel Controller I thought could no be improved, I have had an Old Sunworks 8amp ish controller since and our three amp batteries were mostly sitting at Its been totally reliable, and allowed me to run a watt Rage Saw via an inverter.
These Sunworks controllers are simple to install, they have a very clear display, with all the information you need. If you need a Solar Controller for your Summerhouse, Boat or Caravan, you wont go wrong with Sunworks, and there is great advise if you need it. Years on even the old one I had is still working, which has been re-sited in my garage on an 80watt panel to charge the car battery etc.
Im very pleased with the reliability of these Sunworks Controllers. H Edis — April 16, An excellent product.Skip to main content of results for "solar controllers". Filter results by your vehicle:.
