Safiery Jupiter C – 48V 3000W inverter, 125A DC-DC, no battery48V canopy power pack with 3,000VA inverter/charger, battery not included

Overview

Jupiter C is the 3,000VA member of the 48V Jupiter packs and comes without battery, for builders who supply their own 48V bank. A Victron MultiPlus-II 48/3000/35-32 handles inverting and mains charging, while a Scotty AI 1500W V3 converter links the vehicle's 12V alternator with the 48V battery at up to 125A and feeds the 12V circuits. Solar runs through a SmartSolar MPPT 100/20, and twelve STAR-Light channels switch the canopy loads.

• Victron MultiPlus-II 48V, 3,000VA (C) or 5,000VA (D)
• Scotty AI 1500W 12–48V bidirectional DC-DC, 125A
• SmartSolar MPPT 100/20 for 12, 24 or 48V
• Cerbo GX MK2 with GX Touch 50 display
• STAR-Light 12-channel switching with IP67 SP8 keypad
• Jupiter D also offered with 3× 48V lithium

How it works

Jupiter C and D move the canopy's service battery to 48V while the vehicle keeps its 12V alternator. A Safiery Scotty AI 1500W V3 bidirectional DC-DC converter, rated 125A on the 12V side, charges the 48V bank while driving and in the other direction supplies the 12V circuits from it. The 48V bank feeds a Victron MultiPlus-II inverter/charger: the 48/3000/35-32 in Jupiter C, the 48/5000/70-50 in Jupiter D.

Scotty AI works through the alternator's own regulator and does not modify the alternator. A temperature sensor fitted to the alternator housing lets its machine-learning routine log the normal temperature range; when readings move outside it, Scotty steps down one level, from Hard to Medium, Medium to Soft and Soft to Off, protecting the alternator under sustained load.

What is inside

Both packs share a SmartSolar MPPT 100/20 rated for 12, 24 or 48V batteries, a Cerbo GX MK2 with GX Touch 50 display, a Smart BatteryProtect 12/24V-65A on the 12V side, a 15A AC inlet and outlet, and twelve 10A channels of STAR-Light V2 switching operated from an IP67 STAR-Switch SP8 keypad. Jupiter C is supplied without battery; Jupiter D is available without battery or with three Safiery Solid State Lithium 48V 53.1Ah 2C packs.

Installation and compatibility

The 48V MultiPlus-II supports PowerAssist and, with an external current sensor, extends PowerControl and PowerAssist to 50A or 100A. With a CAN BMS battery, DVCC passes charge voltage and current limits from the battery to the Victron chargers. Safiery's support notes apply here too: mains charging will not start on a supply with an earth fault, and the inverter stays off while it is switched to charge only.

Monitoring and settings

The Victron devices are set up with VictronConnect and shown on the GX Touch 50 through the Cerbo GX MK2; with internet access the VRM portal adds remote monitoring, settings and firmware updates. Scotty AI appears on recent GX displays and has its own browser pages for tuning. Bluetooth Ruuvi temperature sensors and STAR-Tank radar tank sensors can be enabled on the same GX.
