Enerdrive EN55050 ePRO+ Battery Monitor
For owners running more than one battery bank, or wanting the kind of precision a serious off-grid setup deserves, Enerdrive's ePRO+ takes a more traditional wired-shunt approach to monitoring — built to track multiple banks rather than just a single house battery.
Key features
- Measures DC current up to 600A (500A continuous) via an active shunt
- Monitors voltage up to 70Vdc
- Capable of tracking up to three separate battery banks
- Compatible with lead-acid and LiFePO4 chemistries
- Robust M10 stainless steel shunt terminals for a secure long-term connection
RV use case
This suits more complex electrical setups — houses batteries plus a separate starting or auxiliary bank, or larger motorhome builds where knowing exactly what each bank is doing matters. The higher voltage and current ceiling gives it headroom that a basic single-bank monitor doesn't have, which is relevant for owners running larger inverter systems or multiple charge sources feeding in simultaneously.
Pros
- Multi-bank monitoring suits more complex electrical systems than a single-battery setup
- High current and voltage ceiling gives real headroom for larger systems
- Robust terminal hardware suited to a permanent, serious installation
Cons
- More capability than a simple single-battery van or caravan setup actually needs
- Wired shunt installation is more involved than a wireless Bluetooth monitor
- Best value is realised in multi-bank systems rather than a single house battery
Best for
Owners running multiple battery banks or larger, more complex electrical systems — bigger motorhomes, serious off-grid builds, or setups with separate house and auxiliary banks.
Verdict
For a single simple house battery, this is more monitor than you need — but for anyone running multiple banks and wanting genuine visibility across all of them, the EN55050's extra headroom and multi-bank tracking earn their place.
