Victron - BlueSolar MPPT Charge Controller 100/30 [SCC020030200]

The same mid-range MPPT charging as the SmartSolar — without built-in Bluetooth. The Victron BlueSolar MPPT 100/30 and 100/50 use identical charging hardware to the SmartSolar versions: ultra-fast Maximum Power Point Tracking, a multi-stage adaptive algorithm, and up to 98% efficiency on a 12 V or 24 V bank. The one difference is that Bluetooth isn't built in — add a VE.Direct Bluetooth Smart dongle for wireless setup, or configure over VE.Direct with a GX device. Want Bluetooth out of the box? Choose the SmartSolar version.

Who the BlueSolar MPPT 100/30 & 100/50 is built for

• Cruising sailboats — bimini and arch arrays in the 300–1,400 W range, where fast tracking beats rigging and sail shadow.
• Mid-size RVs, vans, and overlanders — a roof of two to four panels charging a 12 V or 24 V house bank.
• Small off-grid cabins and tiny homes — a growing array that has outgrown an entry-level controller.
• Budget-conscious and GX-monitored builds — the same charging as the SmartSolar; if you run a Cerbo GX you monitor over VE.Direct anyway.

How to read the model number

• First number = max PV input voltage. 100 V on both — enough for one or two panels in series.
• Second number = max charge current to the battery. 30 A on the 100/30, 50 A on the 100/50.

Combine those with the maximum PV wattage your system voltage supports to size the controller. Wesley walks the whole process in our MPPT sizing guide.

Both support 12 V and 24 V battery systems with auto-detection. Neither supports 48 V — for a 48 V bank, look at the BlueSolar 150- or 250-series instead.

Which one's right for your install:

• 100/30. Two 200 W panels on a 12 V sailboat, a single large panel on a van roof, most cruising bimini arrays under ~440 W on 12 V (or up to 880 W on 24 V). The default mid-range pick.
• 100/50. Three or four mid-sized panels on a cabin top, RV roofs running 500–1,400 W, off-grid sheds where you've grown out of the 100/30 but the array is still under ~700 W on 12 V (or ~1,400 W on 24 V).

Why these are the default mid-range picks

• Ultrafast MPPT, up to 98% efficiency. Harvests up to 30% more energy than a PWM controller and up to 10% more than a slower MPPT — the difference is real on a partly cloudy day at anchor.
• Smart partial-shading algorithm. The BlueSolar algorithm scans the whole power curve and locks to the true maximum instead of a local peak — useful with rigging shadow or a roof rack crossing the array.
• VE.Direct port. Connects to a Cerbo GX, Color Control GX, or the MPPT Control display for live data, alerts, and remote access via VRM. Add a Bluetooth dongle for wireless setup from your phone.
• Multi-stage charging for every common chemistry. Eight pre-programmed profiles (lithium, AGM, gel, flooded) selectable from a rotary switch, plus a fully programmable mode. Lithium banks must be set to the correct profile.
• VE.Smart Networking (with a dongle or Smart Battery Sense). Get temperature- and voltage-compensated charging by reading the battery at the bank instead of estimating at the controller.
• Recovers fully discharged banks. Resumes charging on a bank pulled down to 0 V.
• Passive cooling. No fan, no audible noise. Full rated output up to 40 °C (104 °F); rated to operate from -30 °C to +60 °C.
