Solar battery installation — Newcastle & the Hunter
Solar batteries for Newcastle homes, sized to how your household actually uses power — installed by our own electricians across Newcastle, Lake Macquarie and the Hunter.
Battery fit depends on your actual usage, property phase, solar configuration and required backup loads. We compare compatible AlphaESS, GoodWe and EcoFlow models, then state the exact inverter, nominal and usable battery capacity and backed-up circuits in writing.
Adding a battery to existing solar, or building the whole system from scratch — either way it's designed, installed and supported by our Hamilton team, licence 470217C.

Existing inverter, array, switchboard and metering are assessed before a retrofit is proposed.
Backup options keep essentials running when the grid drops out.
Track generation, storage and usage from your phone.
We walk you through current NSW and federal battery incentives.
Our own electricians, one accountable local team, no subbies.
Eligible batteries may receive the federal upfront discount, with a separate NSW incentive for qualifying VPP participation.
Battery incentives guideBatteries we install
Single-phase hybrid system · one or two 13.99 kWh battery modules
We quote the SMILE configuration by exact inverter and 13.99 kWh battery module. One or two modules provide 13.99 or 27.98 kWh nominal capacity. The written quote states the M5/M10 inverter variant, backup limits and the warranty document applying to the exact battery SKU.
Product details
ESA all-in-one · single phase 6/8/10 kW or three phase 10/15 kW · 8 kWh usable modules
We currently build GoodWe ESA systems with 8 kWh usable battery modules. The written design names the exact 8.3 kWh nominal / 8.0 kWh usable module and compatible inverter. GoodWe's 63 A figure is grid bypass on relevant models; it is not 63 A of battery-powered backup.
Product details
OCEAN 2 Plus single phase or OCEAN 2 three phase · 8.03 kWh nominal modules
We currently build OCEAN 2 systems with EcoFlow's 8.03 kWh nominal module. Single-phase Plus and three-phase OCEAN 2 are different inverter families, so the quote names the phase, inverter rating, module count, usable-capacity basis and backed-up circuits. The published 8 kWh battery warranty is 10 years standard with an optional five-year extension; the quote states whether that extension is included.
Product detailsWe check your existing inverter, panel array, phase supply and switchboard first. Some systems suit an AC-coupled battery beside the current inverter; others are better replaced with a hybrid inverter. Older Newcastle switchboards sometimes need work before a battery can connect.
Our own licensed electricians mount the battery, wire it into the switchboard, set up any backup circuits you've chosen, commission the system and show you the monitoring app. We handle the rebate paperwork for eligible systems.

Installed price depends on the exact inverter and battery models, nominal and usable capacity, switchboard and metering work, backup circuits and cable route. Eligible federal discounts should be shown separately from the gross installed price.
It's your evening and overnight usage that decides it, not the size of your solar array. Our estimator compares AlphaESS, GoodWe and EcoFlow configurations against your answers, and a site check confirms it against your bills.
The federal program may discount an eligible battery and a separate NSW incentive may apply to qualifying VPP participation. Eligible households apply for a NSW Home Energy Saver zero-interest loan of up to $15,000 through a participating finance provider; it is repayable finance, not a quote deduction or rebate.
Questions
The right size depends on evening usage, existing solar and future loads. Our estimator compares packages from 14 to 32 kWh; a proper quote confirms it against your bills.
Each range has model-specific phase, inverter, battery, backup and warranty terms. The right fit is decided by your site and loads, not a brand ranking.
Sometimes. We assess your inverter, array, switchboard, metering and the proposed AC- or DC-coupled design before confirming compatibility.
The federal Cheaper Home Batteries Program discounts eligible batteries, and a separate NSW incentive may apply to qualifying VPP participation. Current eligibility and each amount should be shown separately in the written quote.
