The case is rated IP65 and the circuit board is conformally coated against moisture. What it is not is a general-purpose controller, and the limits below are worth reading before you buy.\u003c\/p\u003e\u003ch2\u003eWhy this controller\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIP65 housing with corrosion-resistant terminals and a conformal coating on the board. IP65 means dust-tight and protected against low-pressure water jets from any direction. It is not an immersion rating, so despite the product name, do not submerge it.\u003c\/li\u003e\n\u003cli\u003eRated for up to 10 amps of solar input on a 12V battery. In practice that is one nominal 12V panel.\u003c\/li\u003e\n\u003cli\u003eBattery chemistry is selected with a DIP switch, and flooded, AGM, GEL and LiFePO4 are all supported. Note that the equalisation stage at 15.5V is a lead-acid feature; if you are running lithium, set the switch accordingly so equalisation does not run.\u003c\/li\u003e\n\u003cli\u003eTemperature compensation of -24mV per degree C across -4F to 122F, with a port for an external battery temperature sensor. The sensor is an option and is not included.\u003c\/li\u003e\n\u003cli\u003eStatus is shown by LEDs only. There is no screen, no Bluetooth and no app.\u003c\/li\u003e\n\u003cli\u003eOver-voltage, short-circuit, reverse-polarity and thermal protection, with charging shutting down at 149F.\u003c\/li\u003e\n\u003cli\u003eRich Solar's title calls this the number one waterproof solar controller. No ranking body or publication is named anywhere on the page, so treat that as advertising rather than a finding.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMounting and wiring\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRead this first: the controller uses a common POSITIVE grounding scheme. That is the opposite of the negative-chassis convention on most vehicles, and getting it wrong will damage equipment. If you are unsure how your system is bonded, check before wiring.\u003c\/li\u003e\n\u003cli\u003eThis is PWM, not MPPT. PWM pulls the panel down to battery voltage rather than converting the excess, so a 100W panel will deliver meaningfully less than 100W here. The MPPT controllers elsewhere in this range harvest more from the same panel; this one trades that away for a sealed case and a low price.\u003c\/li\u003e\n\u003cli\u003eMaximum array open-circuit voltage is 25V DC, with a normal operating window of 15 to 22V. That is a single 12V nominal panel and nothing more. Check the panel's Voc at your coldest expected temperature, because cold weather raises Voc and 25V is not much headroom.\u003c\/li\u003e\n\u003cli\u003e12V systems only. There is no 24V mode.\u003c\/li\u003e\n\u003cli\u003eM5 terminals accepting up to 10 AWG stranded wire. Mounts vertically to a flat surface with the three supplied spacers and self-tapping screws.\u003c\/li\u003e\n\u003cli\u003eStandby draw at night is 5mA, which is low enough to leave connected over winter on a healthy battery.\u003c\/li\u003e\n\u003cli\u003eA California Proposition 65 warning applies to this product.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWarranty\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRich Solar's published warranty on charge controllers runs two years and is prorated: full coverage in the first year, 50 percent in the second.\u003c\/li\u003e\n\u003cli\u003eClaims are handled by Rich Solar directly.
