Frequently Asked Questions
Q: What is the difference between the KM105F and the KM160F WiFi battery monitor?
A: The main difference is the current measurement range. The KM105F handles up to 50A (0–5KW power), while the KM160F supports up to 600A (0–60KW power). Both share the same 10–100V voltage range and WiFi/Bluetooth connectivity. Choose based on the total current capacity of your battery or solar system.
Q: How does the WiFi remote monitoring work on the KM160F coulomb meter?
A: The KM160F connects to your home or RV WiFi network and links to a smartphone app. Once connected, you can view real-time voltage, current, power, battery percentage, and amp-hour data from anywhere in the world — not just within Bluetooth range. Bluetooth connection range is up to 10 meters for local monitoring.
Q: Is this voltmeter compatible with solar panel battery banks and lithium batteries?
A: Yes. The KM series supports any DC battery system within the 10–100V range, making it fully compatible with lead-acid, AGM, gel, and lithium (LiFePO4) battery banks commonly used in solar, RV, and marine setups.
Q: Does the KM160F WiFi coulomb meter require a constant power source to operate?
A: The monitor itself consumes only 0.9W of power during operation and runs on 5V DC. It is designed for self-contained installation and does not require batteries — it draws power directly from your electrical system. Batteries are not included.
