EA370 HV Connection — System tariff guide
Who this is for
System-connected sites supplied at high voltage.
How the bill works
You pay fixed and energy charges. The bill also uses the highest kVA reading in set periods.
What solar changes
Solar can reduce daytime grid use. If the highest kVA reading occurs after solar output falls, solar alone will not remove it. Solar does not correct poor power factor.
What a battery changes
A battery can reduce the active-power part of the kVA peak. Check power factor before you size it.
Check before you model
- Confirm this code on a current retailer bill.
- Use 12 months of interval data. Check the time of each billed peak.
- Get kW, kVA and power-factor data from the billing meter.
- Get an engineering review before you select equipment.

Illustrative example
Lower EA370 system capacity by 100 kVA
- This is a high-voltage system connection.
- The new rolling maximum is 100 kVA lower.
- The lower value applies for 365 charge days.
100 kVA × 34.6232 c/kVA/day × 365 days ÷ 100Illustrative network-charge reduction: $12,637.47 a year, excluding GST.This tariff uses the highest qualifying half-hour in the previous 12 months. One lower peak does not remove an earlier maximum. Confirm the retailer pass-through and power factor.
