If your solar panels export power at midday while your EV sits in the driveway, a myenergi zappi is built to fix exactly that. We connect Tauranga solar homes with local registered electricians for zappi installation, sensor setup and a proper eco-mode handover.
The zappi from British maker myenergi earned its reputation as the solar owner's charger. Instead of drawing a fixed rate regardless of what your roof is doing, zappi watches your home's import, export and generation through current transformer clamps, then adjusts charging to soak up surplus solar that would otherwise be exported for a low feed-in rate. On a bright Bay of Plenty day in Papamoa or Bethlehem, that can mean the car charges substantially from your own roof; on a cloudy morning, it tops up from the grid only as much as your chosen mode allows.
Zappi offers three charging modes owners actually use. Eco mode keeps the car charging at a minimum rate, blending solar and grid so sessions do not stall on passing clouds. Eco+ mode aims to charge only from surplus, pausing when the house needs the power or clouds roll in, and suits owners determined to maximise self-consumption. Fast mode behaves like a conventional 7.4kW charger for nights and deadlines. A home battery and a myenergi eddi hot water diverter can join the same ecosystem, with priorities set between car, battery and water heating.
Getting those behaviours right is an installation job, not just a mounting job. The CT clamps must sit on the correct cables at your switchboard, generation and grid readings must be verified, and the charger needs a compliant dedicated circuit with Type B RCD protection under SNZ PAS 6011:2023 guidance, installed by a registered electrician who issues a Certificate of Compliance. We connect you with Tauranga installer partners who fit zappi regularly and will configure and demonstrate the modes with your solar running, not just in theory.
Connect with installers for tethered or untethered zappi units in 7.4kW single-phase form, the standard for New Zealand homes, with 22kW three-phase options for suitable properties. Your installer confirms the right variant for your vehicle, parking setup and whether you prefer a permanently attached cable or a socketed unit with a separate lead.
Accurate current transformer placement is the heart of a zappi install. Your electrician fits grid and generation clamps, verifies readings against your inverter, and configures wireless or wired links where an additional hub or harvi sensor is used, so eco modes respond to real surplus rather than guesswork.
Modes only save money if you understand them. Handover covers when to use Eco versus Eco+, how boost timers work for cheap overnight grid top-ups, and how minimum green level settings trade solar purity against session reliability. You will practise switching modes on your own charger and app before the installer leaves.
If you run a home battery or myenergi eddi, the installer helps set export priorities: car first, battery first, or water heating first, and explains how those choices change on high-generation summer days versus winter. Correct priority settings prevent devices fighting each other and wasting the surplus you installed solar to capture.
Behind the clever software sits ordinary, essential electrical work: a dedicated circuit sized for continuous charging, correct cable sizing for the run to your garage or carport, and Type B RCD protection at the board. This is completed and tested to New Zealand requirements, with certification provided on completion of the installation.
The myenergi app shows generation, consumption, export and charging in one place. Your installer links your account, confirms live data matches your inverter display, and sets boost schedules for your off-peak tariff, so you can verify from the couch that today's drive to Tauranga CBD ran substantially on sunshine.
Share your suburb, inverter brand and size, battery if any, vehicle and parking spot, plus a switchboard photo. Zappi design depends on how your solar connects, so this information lets the installer plan clamp positions and any hub or harvi accessories before quoting accurately.
A local registered electrician partner reviews your system and quotes the zappi install including sensors and any extra monitoring hardware. If your switchboard needs upgrade work before a charger circuit can be added, that is itemised and explained at this stage, not discovered on the day.
On installation day the electrician mounts the zappi, runs the dedicated circuit, fits protection and CT clamps, and connects monitoring. Power interruptions are kept to the board work portion. Most Tauranga installs with existing solar are finished within a day, including configuration time.
Where daylight allows, charging is tested while solar is generating so you can watch the charge rate track your surplus in real time. Grid readings are cross-checked, modes are switched, and a boost charge is demonstrated to prove the car still fills fast when you actually need it to.
You finish with settings suited to the current season and guidance for adjusting them as Bay of Plenty daylight changes. Contact us later and we will reconnect you with your installer partner for tweaks, a second charger, or integrating a battery you add down the track.
Tauranga and the wider Bay of Plenty enjoy high sunshine hours by New Zealand standards, which genuinely favours solar charging, but honesty matters more than hype. In summer, a moderate array can cover a commuter car's daily energy entirely from surplus if the vehicle is home during the day. In winter, shorter days, lower sun angles and higher household heating loads shrink the surplus, and most owners blend Eco mode solar with overnight off-peak grid charging. A well-set zappi handles that blend automatically; it does not repeal the seasons, and any installer promising year-round free driving should be questioned.
Working patterns decide results as much as weather. A car that leaves Pyes Pa at 7am and returns at 6pm sees little weekday sun, so weekend daytime charging and overnight off-peak top-ups carry the load, with zappi still capturing holiday and work-from-home days. Retirees, shift workers and home-based workers in Tauranga often capture far more solar per week. Your installer can look at your inverter's export history and your routine, then predict a realistic solar share before you spend anything on the charger.
Zappi also future-proofs the wider system. Because it coordinates with batteries and hot water diversion, owners who start with panels and a car can add storage later without replacing the charger. With New Zealand's plug-in fleet around 155,000 vehicles in August 2026 and still climbing steeply, Tauranga homes that organise solar, water and transport energy together will feel the petrol price, currently around $3.50 a litre, far less than homes treating each appliance as a separate island.
Your retailer pays a small feed-in rate for midday exports, then sells you evening power at full price to charge the car. Zappi Eco+ mode attacks that spread directly, holding charging for surplus and turning low-value exports into kilometres you would otherwise buy back dearer.
Basic chargers keep pulling full rate while the heat pump, oven and dryer spike demand, risking nuisance trips on modest supplies. Zappi monitors grid import continuously and trims charging to respect your connection limit, so solar smarts never come at the cost of household reliability.
Some owners buy solar-ready chargers that are never configured, then conclude solar charging is a gimmick. Proper CT fitting, verified readings and mode tuition at install are what separate a zappi doing its job daily from an expensive ornament blinking on the garage wall.
