Emlite ECA2.V Single Phase 100A Generation Meter Pulse Output 1000/kWh MID Approved Solar PV FiT SEG with Cover
Emlite ECA2.V Single Phase 100A Generation Meter Pulse Output 1000/kWh MID Approved Solar PV FiT SEG with Cover
The Emlite ECA2.V is a single-phase, direct-connect 100A MID-approved electricity meter with 1000 pulse/kWh output, supplied with an extended terminal cover. It is one of the most widely installed generation meters in UK solar PV installations, used for MCS commissioning sign-off, SEG and FiT generation verification, and single-phase sub-metering up to 100A. The meter measures active energy (kWh) in both import and export directions, displaying registers on an 8-character auto-cycling LCD. The extended cover provides additional wiring space at the terminals — essential in consumer unit enclosures where PV tails run alongside other cabling. Fully MID approved to Class B (1%) per EN 50470-1/3. One of the world's most compact single-phase metering units at 91 × 125 × 40mm.
ℹ ECA2.V — Total Generation Mode Explained
The ECA2.V measures the total electrical output of the generation source as a cumulative kWh figure — it does not distinguish between energy consumed in the property and energy exported to the grid. This is the correct meter for MCS commissioning, FiT generation tariff claims, and SEG agreements on PV-only systems. For systems with battery storage where a net export figure is required, use the bi-directional ECA2 variant instead.

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.
✔ 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.
✔ Ultra-Compact — 91 × 125 × 40mm
At just 91mm tall × 125mm wide × 40mm deep, the ECA2 is one of the world's most compact MID-approved single-phase meters, making it practical in space-constrained consumer units and meter boards. The extended terminal cover adds wiring space without significantly increasing board depth. Wide –40°C to +70°C temperature range covers unheated outbuildings and garage boards. IP52 ingress protection (BS EN 60529) for dust and drip resistance in indoor meter board locations.
✔ 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.

Frequently Asked Questions
Do I need a generation meter for my solar PV installation?
Yes — a MID-approved generation meter is a requirement for MCS commissioning sign-off on any solar PV installation in the UK, and is required by DNOs and energy suppliers to validate generation figures for SEG (Smart Export Guarantee) and legacy FiT payments. Without a MID-approved meter, the installation cannot be officially commissioned and the homeowner cannot register for export payments. Some DNOs also specify the type (total generation vs bi-directional) depending on whether battery storage is present — always check your DNO's connection requirements before ordering.
What is the difference between a generation meter and the import meter fitted by my energy supplier?
The import meter fitted by your energy supplier measures electricity consumed from the grid — it only counts energy flowing into the property. The generation meter (this product) measures the electricity produced by the solar PV array. These are two separate measurements: one records what you buy, the other records what you generate. For SEG payments, the energy supplier typically pays on the generation meter reading (total generated) or the export meter reading (what actually left your property) depending on your tariff. The generation meter must be MID-approved and accessible for reading.
Is this meter suitable for a system with a battery?
For solar PV with battery storage, a simple total generation meter like the ECA2.V is generally not appropriate. When a battery is present and can be charged from the grid (as with most hybrid inverters), a generation meter would incorrectly count grid-charged battery discharge as solar generation — inflating the generation reading. The correct meter for hybrid and battery storage systems is the Emlite ECA2 Bi-Directional, which measures import, export, and NET separately, giving the true net export figure required by MCS and energy suppliers for SEG registration with storage.
Can the pulse output be connected to my inverter's monitoring system?
Yes — the 1000 pulse/kWh output on the ECA2.V's auxiliary terminals is compatible with most inverter and energy monitoring platforms that accept an S0 or open-collector pulse input, including GivEnergy, SolarEdge, Solis, Fox ESS, and myenergi systems. The output is opto-isolated (IEC 62053-31), which prevents ground-loop issues when connecting to external monitoring equipment. Check your inverter or monitoring system's input specifications for pulse type (active high/low, voltage range) and configure accordingly. Two wires connect from the meter's aux terminals to the monitoring device's pulse input terminals.
Does the extended cover affect the meter's IP rating?
The extended terminal cover provides additional wiring space at the terminal block — useful when routing generation meter tails in a consumer unit alongside other cabling. It does not significantly change the IP52 rating of the meter itself, as the cover seals the terminal area. IP52 protects against dust ingress and vertically falling water when the unit is tilted up to 15° — suitable for indoor meter board and consumer unit enclosures. For fully outdoor exposed locations, the meter should be housed in an IP65-rated enclosure regardless of the terminal cover fitted.
