Emlite EMP1-AZ Bi-Directional 3-Phase 100A Generation Meter 1000 Pulse kWh MID Approved Solar PV Three Phase
Emlite EMP1-AZ Bi-Directional 3-Phase 100A Generation Meter 1000 Pulse kWh MID Approved Solar PV Three Phase
The Emlite EMP1-AZ is a three-phase, direct-connect 100A per phase MID-approved electricity meter with 1000 pulse/kWh output — the three-phase equivalent of the bi-directional ECA2. Designed for properties with a three-phase (3×230V / 400V four-wire) electrical supply and three-phase solar PV inverters, it measures 4-quadrant active energy (import and export, active and reactive) across all three phases simultaneously, with registers displayed on the 8-digit LCD. Used for three-phase MCS generation metering, SEG compliance, and commercial solar sub-metering. The opto-isolated pulse output integrates with energy management systems, BMS, and inverter monitoring platforms. MID approved to Class B (1%) active energy and Class 2 reactive energy.
ℹ When is a 3-Phase Meter Required?
A three-phase generation meter is needed when the solar PV inverter is a three-phase model or when the property has a three-phase supply and the inverter distributes across all three phases. Fitting a single-phase meter on one phase of a three-phase inverter would count only one-third of total generation. The EMP1-AZ measures all three phases simultaneously. For single-phase domestic supplies (the majority of UK homes), the ECA2 single-phase meters are the correct choice.

Features & Benefits
✔ MID Approved — Legal for Billing & MCS Sign-Off
MID (Measuring Instruments Directive 2004/22/EC) approval certifies a meter's accuracy for trade, billing, and official use. For solar PV installations in the UK, a MID-approved generation meter is required by DNOs and MCS as the legally valid measurement of exported or generated electricity — a non-MID meter cannot be used for SEG payments, FiT legacy claims, or MCS commissioning sign-off. The Emlite meters carry full MID approval to Class B (1% accuracy, EN 50470-1/3), satisfying all DNO and MCS submission requirements.
✔ 4-Quadrant Measurement — All 3 Phases
The EMP1-AZ measures 4-quadrant active energy — import and export in both directions across all three phases simultaneously. Separate registers exist for each quadrant, all accessible via the optical port. Optional power quality data (per-phase voltage, current, and power) is also readable via the optical port for power factor analysis and grid compliance verification. An energy direction indicator on the display shows instantaneous import/export status as a summation across all three phases.
✔ 1000 Pulse/kWh — Energy Monitor Integration
The 1000 pulse per kWh opto-isolated output on the auxiliary terminals feeds real-time energy data into energy management systems, BMS, AMR data loggers, and smart home platforms. Each pulse represents 1Wh — at 1000 pulses/kWh the resolution supports accurate sub-hourly monitoring. The output conforms to IEC 62053-31 and is electrically isolated, preventing ground-loop issues when connecting to third-party monitoring equipment. Compatible with GivEnergy, SolarEdge, Solis, Fox ESS, myenergi, and most modern inverter monitoring platforms.
✔ 100A Per Phase — Direct Connected — 25mm² Terminals
The EMP1-AZ is a direct-connect (whole current) meter at 100A per phase — no external current transformers required, covering standard three-phase domestic and most light commercial solar PV installations. DIN43857-Part 2 terminal arrangement with 150mm fixing centres. Solid brass terminals with 8.2mm cable entry accepting up to 25mm² tails. Three-phase, four-wire connection: L1, L2, L3, N at 3×230V phase-to-neutral / 400V phase-to-phase.
✔ Optical Port — Tamper Resistant — Solid Brass Terminals
An optical communications port (IEC 629056-21) enables electronic meter reading using a standard probe and software — useful for commissioning verification and commercial AMR reading. The meter is tamper resistant with reverse energy fraud detection and is sealed for life. Solid brass cable terminals (8.2mm diameter) give robust, low-resistance connections at full 100A rating. The meter withstands high-voltage events and 140% overcurrent without failure — important in grid-connected installations that may experience transients.
✔ IP54 — Class B + Class 2 — –25°C to +55°C
IP54 ingress protection (protected against dust deposits and water splashing from any direction) is higher than the single-phase ECA2's IP52, reflecting the EMP1's suitability for more exposed meter board positions. Active energy accuracy is Class B (1%, EN 50470-1/3); reactive energy is Class 2 (IEC 62053-23). Operational from –25°C to +55°C. Dimensions 170W × 200.2H × 65D mm.

Frequently Asked Questions
When is a three-phase generation meter required rather than a single-phase one?
A three-phase generation meter is required when: (a) the solar PV inverter is a three-phase model, which is common for systems above approximately 3.68kWp per phase where the G98 per-phase limit is exceeded; or (b) the property has a three-phase supply and the inverter distributes output across all three phases. A single-phase meter placed on one phase of a three-phase inverter would only count one-third of total generation. The EMP1-AZ measures all three phases simultaneously and totals them into a single kWh figure. For single-phase supplies (the majority of UK domestic properties), use the ECA2 single-phase meters instead.
What does 4-quadrant energy measurement mean?
4-quadrant measurement means the meter tracks active energy in all four combinations of direction and phase: import (active consumed from grid), export (active sent to grid), reactive energy imported, and reactive energy exported. This is more comprehensive than a simple import/export meter, which only tracks active energy. For solar PV, the key registers are active import and export — but reactive energy data (Class 2, IEC 62053-23) is valuable for commercial installations where power factor analysis is required, for G99 compliance monitoring, and for future grid balancing applications. All quadrant values are stored and readable via the optical port.
Is the EMP1-AZ suitable for large commercial solar installations?
Yes — the EMP1-AZ is suitable for three-phase commercial and large domestic solar PV installations up to 100A per phase. At 3×230V nominal, this covers three-phase systems up to approximately 69kW (100A × 230V × 3 phases), which encompasses the majority of commercial rooftop solar installations requiring a direct-connect meter. For very large commercial systems above 100A per phase, CT (current transformer) based metering with appropriate CT ratios and a CT-connected meter would be required instead. The MID approval and Class B accuracy are valid for billing and official reporting in all commercial contexts.
Can I integrate the EMP1-AZ pulse output with my inverter monitoring platform?
Yes — the 1000 pulse/kWh opto-isolated output (IEC 62053-31) connects to energy management systems, BMS, AMR data loggers, and inverter monitoring platforms that accept an S0 or open-collector pulse input. Most commercial-grade three-phase inverter monitoring platforms (Solis, GivEnergy, SolarEdge, Huawei, etc.) can accept a pulse input for independent generation verification. The pulse polarity must be observed when connecting — consult your monitoring platform's wiring diagram for the correct terminal orientation. The optical port (IEC 629056-21) provides an additional communications route for electronic meter reading without requiring a pulse input on the monitoring device.
What cable size can the EMP1-AZ terminals accept?
The EMP1-AZ uses DIN43857-Part 2 terminal construction with solid brass terminals featuring an 8.2mm diameter cable entry — this accommodates meter tails up to 25mm² cross-sectional area, which covers the cable sizes used on the vast majority of three-phase generation and supply connections. The terminal fixing centres are 150 ± 1mm conforming to DIN43857. Two steel-slotted M6 terminal screws secure each conductor. For very large commercial tails above 25mm², consult Emlite technical support regarding terminal options.
