Is $7,900 to install a Sigenergy 10kWh all-in-one battery system a fair price?

Project Details

I am in Sydney, Australia, and my house is a terrace. I have an existing 6.5KW solar system, which includes 6 panels with Enphase microinverters and the remainder on an Opal inverter. My property is single phase, and I don't have a lot of space for a battery. My yearly usage is 3223 KWH (peak 605, offpeak 1576, shoulder 1042) and I feed in 7914 KWH (net). I'm wondering if $5K is a realistic price for a 10KWH battery installation, especially with the new 30% Australian Federal government rebate.

Quote Details

This quote is for the installation of a Sigenergy 10kWh all-in-one battery system. The initial estimate was $4900, but after an on-site inspection, an additional $3000 was added to the price, bringing the total to $7900. The additional cost is due to specific site requirements. - Battery System: Sigenergy 10kWh all-in-one - Location: Outside against the garage (only suitable spot) - Additional Wiring: 40 meters of wiring required due to distance from battery to the front switchboard - Site Preparation: Installation of a slab for the outdoor unit
