{"title":"PWM Solar Controllers","description":"\u003cp\u003eA PWM regulator is the simpler of the two controller types, and for a lot of 12V setups it is the right one.\u003c\/p\u003e\u003cp\u003eIt works by switching the panel to the battery in rapid pulses, so the panel runs at roughly battery voltage rather than at the voltage where it would make the most power. The energy that difference represents is mostly never generated, rather than burned off; the controller has its own small losses on top. On a 12V nominal panel charging a 12V battery over a short run, the gap is small enough to be hard to notice.\u003c\/p\u003e\u003cp\u003eSo the question is whether your setup is one where the gap opens up. Higher panel voltage, panels in series, cold weather, low light and long cable runs all widen it. If none of those describe your rig, a PWM will do the job and you can spend the difference somewhere it matters more. The comparison depends on the configuration, not the chemistry.\u003c\/p\u003e\u003cp\u003eWhat does matter, whichever you choose, is that the regulator is rated above the panel's short circuit current and supports the charge profile your battery actually wants. A cheap unit that holds the wrong float voltage will cost you far more than the money it saved.\u003c\/p\u003e","products":[{"product_id":"hardkorr-15a-waterproof-pwm-smart-solar-regulator-lithium-compatible","title":"Hardkorr 15A Waterproof PWM Smart Solar Regulator (Lithium-Compatible)","description":"\u003cp class=\"p1\"\u003eThe Hardkorr 15 Amp Inline Smart Solar regulator is a sturdy and reliable device specifically designed to work seamlessly with a range of 12V solar panels.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eWith the versatility to accommodate a wide range of battery types, including AGM, Gel, Calcium, Wet and Lithium, this regulator will remain a reliable companion throughout your ever-growing touring set-ups.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eOne of the standout features of this regulator is its smart re-activation technology.
