Precision Engineering
Complete Capability
Professional-grade monitoring with dual-bank capability, hybrid input and complete connectivity - in one compact unit.
.svg){kind=icon}
Native dual-bank monitoring
Two channels. Separate voltage, current, SOC and SOH tracking per bank. Works with any compatible precision shunt, including the KALION K5-SHUNT-150 and K5-SHUNT-500.
Dual-Input Interface
Capacitive touchscreen and four physical navigation buttons work at the same time. Full control in all conditions: wet, gloved or in direct sunlight.
Complete Connectivity
Built-in WiFi and Bluetooth for app control and access on your local network. No dongles or extra hardware.
Status at a Glance from 6 m / 20 ft
Addressable RGB LED strip shows system status from across the cabin, about 6 m (20 ft) away. Programmable colour thresholds per bank.
Premium Tactile Feedback
Every touch input confirmed with tactile feedback.
Eliminates accidental input in high-vibration environments.
MicroSD CSV Logging
Export detailed historical data for troubleshooting, warranty claims and system analysis. No cloud subscription needed.
Tank Level Monitoring
4 inputs for fresh, grey and black water and fuel tanks. Works with standard US and European resistive float senders.
Programmable Relay
SPDT relay output for generator auto-start, low-voltage disconnect and alarms. Fully programmable triggers.

How K5 Fits Into Your Existing System
See how we compare to what you're using now.
Monitor House + Chassis Batteries
Keep your house bank and starter battery monitored independently. Know exactly when to run the generator or fire up the solar.
Track Multiple Banks at Sea
House bank and engine starter monitored on one display. The IP65 front face (when panel-mounted) handles spray and weather, and status LEDs are readable from about 6 m / 20 ft.
Manage Your Off-Grid System
Monitor solar battery bank health, track consumption and export data to optimise your system. Check status from your phone over WiFi or Bluetooth.
Use Cases
RV / Camper
Boat / Marine
Off-Grid Cabin
Frequently Asked Questions
Everything you need to know before you order
K5 is in final validation and certification. We will announce the order date and final price by email. Register your interest to be notified first.
Yes. Both input methods operate simultaneously. Use the capacitive touch screen when convenient, then switch to physical buttons if your hands are wet, dirty, or gloved.
Most systems have a house bank and a starter bank, but most monitors calculate state of charge for only one of them. K5 tracks both, with independent state-of-charge calculations.
K5 adds native dual-bank monitoring, a 3.5" colour touchscreen, WiFi, RGB status LEDs, haptic feedback, microSD logging, 4 tank inputs and a VE.Direct port (Victron integration planned). The Victron BMV-712 is a proven workhorse with excellent software and a wide ecosystem, but has a smaller monochrome display, no WiFi, no touchscreen and no tank monitoring. K5 is designed to work alongside Victron systems.
K5 is built on established components: INA228 20-bit precision ADC, Corning Gorilla Glass, CNC 6061-T6 aluminium bezel and a TCXO real-time clock. 2-year warranty and free firmware updates over WiFi. Designed and engineered in Germany.
The VE.Direct port is built in. Victron integration is planned for firmware v1.5 and will show MPPT and charger data directly on your K5.
KALION K5 (assembled and tested), CR2032 backup battery (pre-installed), 1:1 panel mounting template, 4 spare M2 stainless steel mounting screws, spare IP65 silicone gasket and Quick Start Guide (EN, DE, FR, ES, IT). Shunts (K5-SHUNT-150 or K5-SHUNT-500) are sold separately.
Yes. K5 uses external precision shunts, one per battery bank, for maximum measurement accuracy. Each shunt connects to dedicated screw terminals on the K5 via 4-wire Kelvin sense wiring. You can use the KALION K5-SHUNT-150 or K5-SHUNT-500 (sold separately or in a bundle) or any compatible precision shunt.
2-year limited warranty covering defects. Free firmware updates over WiFi. Email support at contact@kalion.energy, with replies within 24–48 hours.
K5 natively monitors 2 banks. For 3 or more banks you can use multiple K5 units. A 4-bank model is on our roadmap.
