Detailed Description

Smart meters' and other process values.

This structure unites all (two, ANZmodSLAVES) smart meter readings as a meterVal_t array plus some common evaluation and process control values.

The four timing data will mark the the evaluation and forwarding time of the complete structure/information. For the meter read times see the equivalent data in the structure .meterVal, which will be 300 .. 600ms older for the meter's latest read (+1s for every other meter read earlier).

batVolt

float batVolt

Battery voltage by esp8266 module and MQTT.

The value by ESP and MQTT will be corrected by ESP_U_CORR. battery voltage by esp8266 module and MQTT

phPckLimit

float phPckLimit

Actual phase packet switch power limit (/W) water boiler.

Surplus solar energy will be put in a battery storage, in charging an electric car and in the hot water tank, automatically. This ensures in-house-consumption (Eigenverbrauch).

Of all these the water boiler has the highest capacity and mid range power. Most important for Eigenverbrauch is its virtually unlimited availability and fast and fine grained power control. phPckpower is the current value and phPckLimit the actual limit (/W) for heating water.

Start value: PCK_POWER_LIM_DEF

chStLimit

float chStLimit

Actual charging station current limit.

The value is the limit in A per phase set for E-Cars loading their drive batteries. The number of phases depend on the car's loading electronics (hence on data not seldom hard to find). One car may use 1 to 3 phases.

With two cars connected one may have 2..6 phases used. Both cars would get the same current limit, i.e. control pilot (CP) pulse width (PWM). The value (which can't be less than 6A) is an upper limit the cars must obey but the may draw any lower value down to zero. Hence, few cars are no means for fine grained surplus power consumption.

The power limit set so is chStLimit * 230V * nOfPhases (by), where the last factor may be not known. actual charging station current limit (/A every phase)
