Digital meter and ''spin'' backward | DIY Solar Power Forum

I have a small 500w solar array (no net meter) that sometimes is able to produce enough power for me to see the dashed indicator on the meter goes the opposite direction, my Emporia also shows that I am putting power back to the grid. But it is nowhere near enough for me to actually see the meter reading drop even 1 kwh.

6 FAQs about [Forward and reverse power of solar power generation]

What is reverse power flow?

A reversal of the traditional power flow from distribution to transmission system by too much DER penetration is referred as ‘reverse power’ flow in this paper and the interconnecting transformers are of special interest.

How does reverse power flow affect Protection coordination scheme?

The reverse power flow occurs when the production of DG exceeds local load demand or when local demand reduces so that power flows in the opposite direction and causes abnormal performance of the protection system. In this section, the effect of reverse power flow on the protection coordination scheme is analysed.

What happens if you reverse power flow in a low-voltage network?

Reverse power flow in a low-voltage (LV) network can cause instability, such as in the line sections and distribution transformers [19, 20]. The overloading of the distribution transformer is one consequence of a low-load, high-PV penetration network; higher voltages are also seen at low-voltage (LV) and medium-voltage (MV) levels. [21, 22].

Does reverse power flow affect transformer overload?

Why do der generating nodes have a reverse power flow?

Due to the highly unpredictable nature of such VRE sources, in many circumstances, the instantaneous power demand and supply do not always match, and insufficient energy storage capacity at the DER generating nodes leads to reverse power flow towards the grid.

Does reverse power flow affect radial network transformer loadings?

A simulation model of a real urban electricity company in Ghana is investigated against various PV penetration levels by load flows with ETAP software. The impact of reverse power flow on the radial network transformer loadings is examined for high PV penetrations. Using the least squares method, simulation results are modelled in Excel software.
