Solar Power Export Meter

In case of energy flow towards the grid the elgris zero export will reduce the solar system.

Solar power export meter.

Let me use one of my bills as an example to show you what a difference that would make. The answer is a smart meter which can make a recording of your electricity exports on a half hourly basis. This allows you to use more energy for self consumption when the loads are high while maintaining the export limit also when the loads are low. If you already have a smart meter then it will need to be configured so that it can measure the power you export.

Solaredge offers an export limitation option integrated in the solaredge inverter firmware which dynamically adjusts pv power production. Fortunately the uk government is currently carrying out a nationwide rollout of smart meters. Then they could present a bill that showed all your savings. If you have an old accumulation meter then you will need to upgrade to a smart meter.

If the electricity retailers cared about their customers knowing what s really going on they could plug a 20 device called a current transformer into your meter to measure your solar output. Export limiting severely impacts the data that you can see from your solar system making it nearly impossible to know how your system is performing. Firstly if your solar inverter provides monitoring the inverter will only report what is produced limited to 5kw not what could have or should have been produced. The smart meter will communicate directly with the energy supplier enabling them to pay exactly what they owe.

When there is a positive balance in the system all solar energy is being used within the installation.
