From one bill to two fair shares
Solar Split measures who used what, every few minutes, then applies the tariff and the sharing rules you agreed.
- Solar only
- Solar + battery
- Battery only (coming soon)
What you need
Solar Split can only work out a fair split if at least one dwelling on the connection has its own consumption meter. The other dwelling's use is the site total minus the metered dwelling.
A meter on one dwelling
It reads one home's own use. A second meter makes the split more accurate.
A way to read the whole site
Total consumption, or grid import and export, plus solar production. A solar inverter or gateway with consumption clamps does this, and so does a whole-site meter.
Without a meter on a dwelling the split cannot be calculated. The Home Kit has the hub only; your electrician installs the meter.
The meter must be one of the supported models listed on the Equipment page; unsupported meters cannot be read by the hub.

What goes into the split
Each home's own use
Running totals for each home, solar and battery, so gaps can be checked.
The tariff
Time-of-use bands, supply charge and feed-in credit from your retailer plan.
Your sharing rules
How solar, the supply charge and battery energy are shared, applied the same way every month.
Checks against the retailer
Totals reconcile to the metered import on the bill, so the shares add up to the cent.
What Solar Split is not
It is a calculator and a record. It does not sell you electricity, send bills, hold money or change how your home is metered.
