Tier 2 — Crew

Our flagship. A solar power unit built for small teams — mid-size construction sites, mid-size events, dairy support, vineyards and event hospitality. 2.85 kW of 475 W panels, 10 kWh of LiFePO₄ storage, a 6 kW inverter and a 16 A / 32 A switchboard. Choose a 3.4 m trailer, which tows on a standard Class 1 (car) licence, or skids for a fixed static install. The workhorse of the rental fleet.

Built for

Compliance

Where you choose the trailer option, our solar systems are installed onto purpose-built trailers that are supplied engineered and road-legal — NZTA Class TB light trailers (GVM under 3,500 kg) with a current Warrant of Fitness (WoF) at the time of delivery. The solar, battery, inverter and 230 V electrical systems are installed by EWRB-registered electricians and independently inspected by a Licensed Electrical Inspector, with a Certificate of Compliance issued for every unit — trailer or skids. Trailer builds tow on a standard Class 1 (car) licence, provided your combined vehicle-plus-trailer weight (GCM) stays within your licence limit (6,000 kg on a full Class 1) — check your tow vehicle against the trailer's weight before towing. Skid-mounted builds are static, non-towable installs placed or craned into position, so trailer registration, WoF and towing requirements do not apply to them.

Frequently asked

When does Tier 2 ship?
Every unit is built to order. Indicative build time for Crew is 40 days from order confirmation, subject to final build specification.
What sites does Tier 2 cover?
An 8-house residential build, mid-size event, dairy support, vineyard or hospitality event. Use the calculator on the homepage with your real load profile to confirm.
Trailer or skids?
Both are available. The 3.4 m trailer from NZ$30,186 ex-GST is the mobile option. Skids, from NZ$23,686 ex-GST, are a lower-cost non-towable static option for fixed or craned installs where the unit stays in one place.
Can I expand it later?
Solar can be lifted from 2.85 kW to 5.7 kW with up to six floor-mounted 475 W panels, battery from 10 kWh to 20 kWh (four 5 kWh modules), and inverter from 6 kW to 12 kW (two units). An enclosed 2 m × 2 m cargo bay is an optional extra at +NZ$4,290 ex-GST. Add-on modules — irrigation pump, espresso & hospitality, PA & lighting, tool & charging, and insulated chiller — are planned as future optional extras rather than standard equipment.
Bad-weather backup?
Tier 2 ships with 10 kWh of battery storage, expandable to 20 kWh — actual runtime varies with load and battery size. A hybrid LPG module may be offered for hire for multi-week winter deployments, or you can pair two units.
White-label or fleet supply?
Yes — fleet supply available for hire businesses, civil-defence buyers, and corporate sustainability programs. Email power@solartrailer.co.nz.
