CrimpRenogy Wanderer 30A
Entry-level 30A PWM controller for 12V systems only. PV input is limited to 25V, so use 12V-nominal panels; max 400W of array.

A sizing result with its assumptions attached.
Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. 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 3 m one-way run is a stated reference, not a universal installation prescription.

Terminal map
| Terminal | Polarity | Direction | Rating |
|---|---|---|---|
| PV + | positive | input | 35 A |
| PV − | negative | input | 35 A |
| BATT + | positive | output | 30 A |
| BATT − | negative | output | 30 A |
What belongs around it.
- 6 m total of 10 mm² (8 AWG) marine cable
- Four 10 mm² cable lugs matched to the equipment studs
- 40 A fuse and holder on the positive run
- Heat-shrink, strain relief, and terminal boots sized to the cable

The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.
Engine reference
Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
