Belgrave is open at roughly 950 people per square kilometre, where larger homes use more in the evening and a battery has more to do. Sizing to actual overnight consumption matters here. At roughly 200 metres, Belgrave is in the ranges. Backup capability, not storage capacity, is usually the deciding specification.
Belgrave sits about 36 kilometres out in Yarra Ranges. Electric vehicles are more common here, and charging pattern changes the right battery size. Yarra Ranges covers Belgrave. Council only matters where equipment would be visible on a heritage-controlled frontage.
Because Belgrave backs onto Belgrave Heights and Belgrave South, a second visit is rarely a second trip for us. Belgrave spans roughly 4.1 square kilometres of Yarra Ranges. Postcode 3160, and 3894 people at the 2021 census.
For what it is worth on site: Though originally the area was known as "Monbulk" for the reservoir that lay near by, the town wasn't known as Belgrave until December 1904 when the railway station was renamed, and another suggested name for the town at that stage was Glassford. Older homes need more board work before a battery goes in. Day to day we are across Belgrave and the streets either side of it: Belgrave Heights, Belgrave South, Kallista and Selby. Same crew, same rates, same certificate at the end.
Belgrave is approximately 8.3 kilometres south-east of Boronia. We cross that distance most weeks, so there is no premium for it on your quote. Belgrave has Belgrave railway station, and a station usually means older commercial frontage nearby and a mix of housing eras spreading out from it.
A second note on how the suburb came to be: === Puffing Billy Railway ===
Belgrave's most notable attraction is the heritage narrow gauge, steam-operated Puffing Billy Railway, which was reopened in 1962—after four years of restoration by volunteers—and travels through 24 kilometres (15 mi) of cool temperate rainforest, semi-urban development and rural farmland to Gembrook.
