CrimpVictron MPPT 100/50
MPPT solar charge controller. 50A output, max 700W @ 12V / 1400W @ 24V, 100V PV. Keep the array's cold-weather Voc under 100V.

How the MPPT 100/50 is wired
The run drawn here is the 10 ft reference run sized below. Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. Confirm your own run length, routing and terminations before ordering — open this part in the designer to size it against your actual system.
What size cable and fuse does the MPPT 100/50 need?
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The design current is the unit's rated output. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 10 ft one-way run is a stated reference, not a universal installation prescription.

Installation notes from the field
What it does
MPPT solar charge controller: takes a solar array of up to 100 V open-circuit and charges a 12 V or 24 V battery at up to 50 A. Nominal PV power is 700 W on a 12 V bank and 1400 W on 24 V; battery voltage is detected automatically, and Bluetooth plus a VE.Direct port handle setup and monitoring.
Wiring it
The PV side connects to the array (max short-circuit current 60 A per the datasheet); the battery side goes to the bank through its own fuse. The controller charges whatever the battery side reads on first power-up, so connect the battery before the panels.
What people get wrong
Sizing the string by its rated Voc at 25 °C. A panel's open-circuit voltage rises as temperature falls, and the 100 V input limit applies on the coldest morning of the year — not in the datasheet's test conditions. Three 12 V-nominal panels in series can sit comfortably under 100 V in summer and exceed it below freezing. Size the string so cold-weather Voc stays under the limit, or use fewer panels in series.
Supporting parts
- PV disconnect between array and controller, rated for the string voltage
- Battery-side fuse at the bank end of the charge run
- MC4 connectors and PV wire on the array side; tinned marine cable on the battery side

Engine reference
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
