{"product_id":"bravo-legend-40-40-amp-pwm-solar-charge-controller","title":"BRAVO LEGEND 40 - 40 Amp PWM Solar Charge Controller","description":"\u003cp\u003eA 40-amp PWM controller for a 12V or 24V battery bank that sits somewhere dry — inside an RV, a van cabinet, a cabin wall, or a boat locker. It reads the battery voltage on connection and configures itself, so the common mistake of running a 24V bank on a 12V setting is largely designed out. At 40 amps it handles roughly 600 watts of panel on a 12V system or 1200 watts on 24V.\u003c\/p\u003e\u003ch2\u003eWhy this controller\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAutomatic 12V\/24V detection on first connection, with a manual override if you would rather set it yourself.\u003c\/li\u003e\n\u003cli\u003eCharging profiles for sealed, GEL, flooded and lithium banks, selected from the front panel rather than by DIP switch.\u003c\/li\u003e\n\u003cli\u003eThree-stage charging — boost, float and equalisation. Note that equalisation runs on flooded lead-acid only; it is disabled for GEL and lithium, as it should be.\u003c\/li\u003e\n\u003cli\u003eTemperature compensation at -3.0 mV\/°C per 2V cell, which also correctly excludes lithium.\u003c\/li\u003e\n\u003cli\u003eFive load-output modes: light control with a ten-minute delay, light control plus a 1–14 hour timer, manual, debug and always-on. That makes it usable as a dusk-to-dawn lighting controller, not just a battery charger.\u003c\/li\u003e\n\u003cli\u003eProtection covers overcharge, over-discharge, overload, short circuit and reverse polarity, plus TVS surge suppression.\u003c\/li\u003e\n\u003cli\u003eUL1741 certified, with the certificate published for download — worth noting, because several controllers in this same range are not.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat it will not do, plainly\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis is PWM, not MPPT.\u003c\/strong\u003e A PWM controller pulls the panel down to battery voltage rather than converting the surplus, so a panel with a Vmp well above your battery voltage loses that difference as unused headroom. If your panels are nominal 12V or 24V units, that penalty is small. If you are feeding it a 60- or 72-cell panel intended for grid-tie, an MPPT controller will return noticeably more energy and is the better buy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum solar input is under 55V.\u003c\/strong\u003e That is a real ceiling, and open-circuit voltage climbs in cold weather, so size the string with a margin rather than to the number.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe IP30 rating is indoor-only.\u003c\/strong\u003e Rich Solar's own page describes IP30 as \"dust\/splash resistant,\" which is not what the rating means — the second digit of IP30 is zero, so there is \u003cem\u003eno\u003c\/em\u003e water ingress protection at all. Mount it somewhere it will never be rained on or splashed. If the controller has to live outside or in a wet locker, buy a sealed unit instead.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth is described as optional.\u003c\/strong\u003e The specification sheet lists a Bluetooth module and an LCD, but the manufacturer's own copy calls Bluetooth \"optional\" without saying whether a dongle ships in the box. Confirm with us before ordering if remote monitoring is the reason you are buying it. The LCD itself is built into the unit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBRAVO LEGEND 40 or BRAVO LEGEND 30\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe two are the same box. Identical case dimensions (6.46 × 4.07 × 1.85 in), identical 0.86 lb net weight, identical input ceiling, identical feature list.\u003c\/li\u003e\n\u003cli\u003eThe only difference is capacity: 40A and 600W at 12V here, against 30A and 450W on the LEGEND 30.\u003c\/li\u003e\n\u003cli\u003eThe step up costs about sixteen dollars and buys 150 watts of extra array headroom at 12V. If you are near 400W today and might add a panel later, take the 40. If your array is settled at 300W or less, the 30 does the same job.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWire battery first, then solar, then load — this is how the controller detects system voltage.\u003c\/li\u003e\n\u003cli\u003eMount vertically on a solid surface with clear air above and below; the case is passively cooled.\u003c\/li\u003e\n\u003cli\u003eKeep the run from controller to battery short and correctly sized. Voltage drop on that leg is read by the controller as a low battery and will hold charging voltage higher than it should be.\u003c\/li\u003e\n\u003cli\u003eFuse the battery leg close to the battery.
