The circuit board is conformally coated and the terminals are corrosion-resistant, which is the actual reason to choose it over a cheaper controller. It is a 12V-only unit and the array side is limited to 25 volts, so it is a controller for a small, simple, parallel-wired array.\u003c\/p\u003e\u003ch2\u003eWhy this controller\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConformally coated internal board and corrosion-resistant terminals and connectors — protection against moisture on the inside, not just the case.\u003c\/li\u003e\n\u003cli\u003eGenerously sized power terminals: 8 AWG stranded, torqued to 17 in-lb. That is properly rated for 30 amps, where many controllers in this class top out at 10 AWG.\u003c\/li\u003e\n\u003cli\u003eWill wake a lithium battery that has shut down under BMS protection, which matters on a boat or a vehicle left standing for months.\u003c\/li\u003e\n\u003cli\u003eDigital display of charging parameters and battery settings, with LED status indication.\u003c\/li\u003e\n\u003cli\u003eBattery profiles for flooded, AGM, GEL, calcium and lithium.\u003c\/li\u003e\n\u003cli\u003ePort for an external battery temperature sensor. The sensor itself is optional and not supplied.\u003c\/li\u003e\n\u003cli\u003eOver-voltage, short-circuit and reverse-polarity protection, plus thermal protection.\u003c\/li\u003e\n\u003cli\u003eUL1741 certified, with the PWM-series certificate published for download.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat it will not do, plainly\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 volts only.\u003c\/strong\u003e There is no 24V mode. If your bank is 24V, or might become 24V, this is the wrong controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum array voltage is 25 VDC open-circuit.\u003c\/strong\u003e That is a low ceiling and it has a hard consequence: \u003cem\u003ewire panels in parallel only, never in series.\u003c\/em\u003e A pair of nominal 12V panels in series will exceed it. Open-circuit voltage also rises in cold weather, so a panel rated 22V Voc at 25°C can approach the limit on a freezing morning. In practice that means around three 100W nominal-12V panels to reach 30 amps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP22, not weatherproof.\u003c\/strong\u003e IP22 protects against fingers and vertically dripping water. It is not a sealed unit and must not be mounted where rain or spray can reach it. If the controller has to sit outside, buy from the sealed BRAVO Waterproof range instead.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePWM, not MPPT.\u003c\/strong\u003e The controller pulls the array down to battery voltage rather than converting the surplus. With three panels the energy you give up starts to be worth real money over a season, and if you can keep a controller dry, an MPPT unit is the better long-term buy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\"Designed to meet CE standards\"\u003c\/strong\u003e is the manufacturer's own phrasing on EMC and FCC compliance. That is a design statement, not a certification claim, and we are not going to restate it as one. The UL1741 certificate is real and downloadable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIs this the right 30-amp controller for you?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOur BRAVO LEGEND 30 costs less than half as much\u003c\/strong\u003e and is more capable on paper: 30 amps as well, but 12V \u003cem\u003eand\u003c\/em\u003e 24V, a 55V array ceiling instead of 25V, three-stage charging with equalisation, and temperature compensation. If your installation is dry and indoors, buy that one and keep the difference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChoose this unit instead\u003c\/strong\u003e if the environment is the problem rather than the electronics — a coated board, sealed-grade terminals and a thin case for a tight bulkhead are worth paying for on a boat. That is the whole argument for the price, and we would rather say so than dress it up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote on naming:\u003c\/strong\u003e Rich Solar sells an MPPT controller also called the BRAVO 30. They are different products. This is the PWM version; check the SKU (RS-PWM30F) if you are cross-shopping.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVertical wall mounting, on a solid surface.\u003c\/li\u003e\n\u003cli\u003eCommon positive grounding — check this against the rest of your system before wiring, particularly on a vehicle with a chassis-negative ground.\u003c\/li\u003e\n\u003cli\u003eTorque the power terminals to 17 in-lb.
