Multi MSEI-100C Solar Power Generation Equipment DC Circuit Insulation Diagnostic Equipment

Manufacturer: Multi Measuring Instruments Co., Ltd.
Model: MSEI-100C
Features
- The MSEI-100C is an insulation ohmmeter.
- Measures insulation resistance of DC circuits (between the battery panel and the power conditioner) in a photovoltaic installation with a live wire.
- Can determine insulation deterioration between modules.
- Equipped with a diagnostic function that identifies the section of insulation degradation (P side, N side, and module).
- First device with this section-identification diagnostic capability.
Specifications
Detection methods | Ground DC voltage measurement with standard resistors. |
---|---|
Measurement Items | Generated Voltage [DCV] / P-phase Isolation Resistance / N-Phase Isolation Resistance / P/N-Phase Isolation Resistance / Inter-module Isolation Resistance |
Measuring range | Insulation Resistance: 0.01MΩ~19.99MΩ |
Generated Voltage: DC0.1V~599.9V | |
How to determine | When the insulation resistance of each phase falls below 1MΩ, the LED lamp flashes a red light at the insulation defect. If there is no problem with the insulation resistance, the green light will turn on. |
power | AA alkaline battery×4 |
Dimensions and weight | W190×H140×D42mm Approx. 800g |
accessory | Complete measuring probe, mobile case |
option | AC Adapter |
