Its dual-bank design charges your main house bank and trickles a second starter battery at the same time. RV-C ready, and it runs lead-acid or lithium.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Go Power SC-DB-MPPT-30-12 is a 30-amp MPPT solar charge controller built for people who live off their batteries. It sits between your solar panels and your battery bank, and its whole job is to squeeze every usable amp out of the sun and put it into your batteries without cooking them. If you're running a rig with rooftop panels, a decent house bank, and maybe a fridge and some lights you'd like to keep alive without shore power, this is the kind of controller you wire in and mostly forget about.\u003c\/p\u003e\n\u003cp\u003eHere's what MPPT actually buys you. A basic PWM controller just connects the panel straight to the battery and throws away the voltage difference. This one tracks the panel's maximum power point and converts that extra voltage into extra charging current, up to about 98% efficiency. On a cold, bright morning, when panel voltage runs high, that's real amp-hours you'd otherwise lose. Over a season of boondocking it adds up.\u003c\/p\u003e\n\u003cp\u003eThe controller handles up to 600 watts of solar input on a 12-volt system and pushes up to 30 amps into the battery. That's a comfortable match for roughly three 200-watt panels or a similar rooftop array. Battery operating voltage runs from 8 to 32 volts, so it stays awake even when a bank has been pulled way down.\u003c\/p\u003e\n\u003cp\u003eThe \"DB\" in the part number is the dual-bank feature, and it's the reason a lot of folks pick this unit. Besides charging your main house bank, it can trickle up to 2.5 amps into a second battery, usually the chassis or starter battery. So the same panels that keep your house bank full also keep your start battery from going flat while the rig sits. No second controller, no manual switching.\u003c\/p\u003e\n\u003cp\u003eBattery chemistry is covered both ways. Run flooded, AGM, or gel lead-acid and the controller applies temperature compensation at -3mV per degree C per 2 volts, so charge voltage tracks the weather. Switch to lithium and it uses a LiFePO4 profile with temperature compensation disabled, which is exactly what a lithium bank wants. Pick the right profile at install and you're set.\u003c\/p\u003e\n\u003cp\u003eIt's also RV-C network compatible, so on a coach that speaks RV-C it reports right into the system. Want to watch your numbers on your phone? Bluetooth and app monitoring are available when you add the optional display kit, so you can check charge state and history without crawling into the bay where the controller lives.\u003c\/p\u003e\n\u003cp\u003eProtection is layered in. You get reverse-polarity, over-temperature, internal overvoltage, PV overcurrent, and reverse-current protection, so a wiring slip during install or a hot afternoon in a sealed compartment won't take the unit out. It's rated for a wide -40 to 140 degree F operating range, and it's FCC Part 15 Class B and RoHS compliant. The housing measures 7.55 by 6.97 by 2.6 inches, small enough to tuck near the batteries.\u003c\/p\u003e\n\u003cp\u003eA couple of install notes from experience. Size your wiring for the full 30 amps over the run you actually have, don't just grab whatever's in the parts bin. Fuse both the solar input and the battery output close to the battery. And if you're on lithium, set the lithium profile before you connect the bank, because the lead-acid default isn't what a LiFePO4 pack should see day after day.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Van and RV owners, off-grid trailers, and anyone with a mixed house-and-start battery setup who wants one controller doing both jobs. Who's it not for? If you're only running a single small panel to a single small battery, you don't need this much controller. But if you've got a real array and you care about getting the most out of it, the SC-DB-MPPT-30-12 earns its spot.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e30A maximum charge current, a comfortable match for roughly 600 watts of 12-volt solar\u003c\/li\u003e\n  \u003cli\u003eMPPT tracking at up to 98% efficiency, harvests more amp-hours than PWM on cold, bright days\u003c\/li\u003e\n  \u003cli\u003eDual-bank output keeps your house bank full and trickles up to 2.5A to a second starter battery\u003c\/li\u003e\n  \u003cli\u003e8 to 32V battery operating range works with 12V lead-acid and LiFePO4 lithium banks\u003c\/li\u003e\n  \u003cli\u003eRV-C network compatible, reports right into a compatible coach system\u003c\/li\u003e\n  \u003cli\u003eBluetooth and app monitoring available with the optional display kit\u003c\/li\u003e\n  \u003cli\u003eTemperature compensation at -3mV per degree C per 2V for lead-acid, disabled for lithium\u003c\/li\u003e\n  \u003cli\u003eFive-way protection: reverse polarity, over-temperature, internal overvoltage, PV overcurrent, reverse current\u003c\/li\u003e\n  \u003cli\u003eWide -40 to 140 degree F operating temperature range for hot bays and cold storage\u003c\/li\u003e\n  \u003cli\u003eFCC Part 15 Class B and RoHS compliant\u003c\/li\u003e\n  \u003cli\u003eCompact 7.55 x 6.97 x 2.6 inch housing tucks in near the batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Go Power reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow big a solar array can this controller handle?\u003c\/summary\u003e\n    \u003cp\u003eOn a 12-volt system it takes up to 600 watts of solar input and puts out up to 30 amps to the battery.
