About this deal
Due to its sturdy construction, we categorize this as the best option if you’re going off-grid. Plus, it’s one of the most reliable options you’ll find.

Power Energy Syst. 62, 221–228 (2014). https://doi.org/10.1016/j.ijepes.2014.04.040 To select a solar charge controller, you need to know the type of system you’ll be using it with, whether it be a 12, 24, 48-volt, or 110-volt/220-volt AC system.

Neither is necessarily “better” than the other — each has advantages depending on climate, array size, and system components.Zadeh, L.A.: Fuzzy sets. Inf.

While it may appear that a 12-volt panel would be compatible with a 12-volt battery bank, that’s not the case. Most panels don’t actually run at their rated voltage because the power generated by the sun can vary depending on different factors, such as how bright the sun is.

For more information about PWM or MPPT charge controllers, read our whitepaper: which solar charge controller: PWM or MPPT? This can be used to monitor and regulate two independent (electrically isolated) batteries at the same time.

An MPPT controller can accept and modulate varying voltages. They harness excess power that a PWM would otherwise waste. Who Needs a Solar Charge Controller?

Institute for Operations Research (IOR), Stochastic Optimization (SOP), Karlsruhe Institute of Technology, Karlsruhe, Germany Which leads to my second question - if I wasn't imagining things, and the 36v controller I was using was only drawing 36v (I know - I know nothing!) and thus was indeed perfectly safe to use in that way, and yet the performance (speed, on the flat and up the hills near me) was exactly the same (or as far as I can tell), does that mean I'd get greater range from using the 36v controller in the same set up as I'm now using the 48v controller? Rashid, M. H. (2010). Power Electronics Handbook: Devices, Circuits, and Applications Handbook. Academic Press (3ed.). Elsevier. pp.488–490. ISBN 978-0123820365. Most battery charging units fall within the 12-48VDC range. However, some may need a capacity of 60V or 72V. For those looking to power smaller loads, like lights and small appliances, LOAD or LVD outputs are good options. The load terminal has a low voltage disconnect and will turn off a connected device to keep the battery from being expired.
