Victron SmartSolar MPPT 150/60 wiring diagram
Charge a house battery from a larger solar array. Check the Tr or MC4 version, follow the power connections, and confirm array limits before startup.

Connection essentials
Check Tr or MC4
Identify the Tr or MC4 version. Two MC4 pairs feed one tracker and retain a separate current limit per pair.
Battery before solar
Connect the protected battery circuit first, wait 10 seconds and verify system voltage before connecting PV and controls.
Check the array limits
Check cold-weather array voltage, operating voltage and aggregate short-circuit current separately. House loads connect through their own battery circuits.

Battery-side sizing for this example
These values describe the battery charge circuit. Match Tr or MC4 hardware and check the complete array before selecting PV wiring and protection.

12 V system
- Wire
- 25 mm² · 4 AWG
- Example fuse
- 80 A

- Voltage drop
- 2.1%
Sized against ABYC E-11. The design current is the unit's rated output. The length is one way; voltage drop includes an equal-length return.
Run-length and manufacturer assumptions
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.
Supporting parts
- 6.1 m total of 25 mm² (4 AWG) marine cable
- Terminations for 25 mm² cable, matched to the equipment's screw terminals, leads or studs
- 80 A fuse and holder on the positive run
- Heat-shrink, strain relief and terminal boots sized to the cable
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.

Is this the Tr or MC4 version?
The catalog photograph shows the SmartSolar 150/60-Tr, with screw terminals. Check your label: the shared manual also covers the MC4 version, whose PV connector limits differ.
Both charge at up to 60 A. Nominal PV power is 860 W at 12 V or 3440 W at 48 V. Battery voltage detection is automatic for 12/24/48 V; select 36 V manually.
Where do the array, battery and house loads connect?
Connect the array to PV + / PV − and the battery circuit to BATT + / BATT −. There is no high-current LOAD output; house loads need separate protected battery circuits.
The connection details depend on the variant:
- Tr: screw terminals accept up to 35 mm² / AWG 2; tighten to 2.4 N·m.
- MC4: two parallel PV connector pairs feed one tracker, with 30 A maximum per pair. They are not independent MPPT channels.
The drawing omits the grounding screw, rotary profile selector, remote on/off connector, programmable relay and VE.Direct port. Remote and relay connections are control circuits, not battery power terminals.
What do I connect first?
Battery first, PV later. With PV isolated, check polarity, connect the battery and wait 10 seconds. Verify system voltage before connecting PV and control wiring, following the installation sequence.
The battery protection table gives a 70–80 A fuse. Locate protection near the battery source and select cable for the actual route and voltage drop.
Mount vertically on a nonflammable surface, terminals downward, with 100 mm clearance above and below, within 3 m of the battery but never above it. The IP22 connection area needs a dry, guarded location; full output is specified up to 40°C.
Which solar voltage and current limits apply?
Check the complete array against each limit:
- 150 V absolute maximum, including open-circuit voltage under the coldest conditions.
- 145 V maximum during startup and operation. Startup also requires PV voltage 5 V above battery voltage, falling to 1 V once running.
- 50 A aggregate PV short-circuit current. This is separate from the 60 A battery-output rating and the MC4 connector limits.
Use the panel temperature coefficient and your series/parallel arrangement; panel nameplate voltage alone is insufficient.
Which charging settings should I review?
Choose a battery-approved preset and current limit in VictronConnect. Confirm absorption, float, equalization and lithium temperature restrictions. The battery's BMS must be able to stop charging where required. After startup, compare battery voltage at the bank and controller and check that current, voltage and temperature readings are plausible.
Fit check
Connect it to the rest of your system.
Describe your setup to draft a system with SmartSolar 150/60 connected. Review the selected parts and cable lengths, then edit the diagram in Crimp.
The model only picks parts and draws the connections. Every wire size and fuse rating still comes from Crimp's own sizing, never from the model.
