Sizing Calculator

Enter your equipment load and site details below for a rough estimate. This is a simplified guide only — for an exact specification, our engineers confirm the real winter solar data for your site and size against your full load profile.

How many days with no sun at all the battery alone must keep the system running

Winter (June–July) peak sun hour midpoints, based on NIWA SolarView regional data as summarised by GridFree. Actual PSH varies with panel tilt and exact site — treat as a starting point, not a substitute for our engineers confirming your specific location.

Daily Energy Use

Approx. Battery Capacity

Approx. Solar Panel Size

Ballpark figures only, assuming lithium batteries at 80% usable depth of discharge and a 75% solar system derate. Regional winter sun hours are approximate midpoints from published NIWA-derived data and can vary meaningfully with panel tilt, orientation and exact site conditions. Actual sizing depends on your exact devices, site shading and confirmed winter solar data from our engineers.

One Supplier for the Whole Off-Grid Power System

More and more equipment across New Zealand's Agri-tech, data telemetry and IoT markets needs to be powered remotely, off-grid.

Many of these businesses build very capable tech and software, but assembling the solar and electrical side of the product often means juggling multiple suppliers, tying up internal resources, and struggling to scale production quickly.

Tell us the DC voltages your equipment needs, the load current, hours of operation, and how many days of autonomy (no sun) you want the system to run for, and we'll deliver a fully finished, integrated solution built to those parameters.

Every Box Is Built to the Same Complete Standard

IP65 or IP67 rated outdoor enclosure, or lockable cabinet

Deep cycle AGM or LiFePO4 battery bank, sized to your load

Solar panel(s) with pole-mounted frame

Solar cable (3m, 5m or 8m) with mating connectors, pre-terminated

Solar charge controller, sized to the panel and battery

Any DC-DC converters needed for devices that won't run direct off the battery voltage

Sized to Your Load, Your Climate, and Your Autonomy Needs

Sized to Your Load, Your Climate, and Your Autonomy Needs

We size every system against four inputs: the DC voltages your equipment needs, the current it draws, how many hours a day it runs (usually 24/7), and how many days of autonomy — no sun at all — you want the system to survive. Battery bank, panel size and charge controller are all selected against those numbers, not a generic template.

Room for Your Equipment, or We Pre-Wire It for You

Room for Your Equipment, or We Pre-Wire It for You

We can leave space in the enclosure for you to fit your own equipment on site, or we can receive your devices and install and pre-wire them into the box ourselves before it ships — reducing the in-house labour and time needed to put the finished unit together.

Built to Scale with Your Production

Built to Scale with Your Production

A single supplier relationship means we can scale production up as your volumes grow, and hold a small buffer stock of finished boxes on repeat-configuration builds to protect your continuity of supply and let you respond quickly to demand.

Common Applications

Solar Box solutions are used wherever equipment needs to run off-grid. The strongest current demand in New Zealand is in Agri-tech and cow monitoring, alongside growing use in water quality sensing — plus gate automation and CCTV, though these markets increasingly see mass-produced solar kits that can struggle to perform through a New Zealand winter.

Agri-Tech & Cow Monitoring

Agri-Tech & Cow Monitoring

New Zealand's strongest current demand for Solar Box solutions — powering cow collars, activity monitors and farm sensors in paddocks with no mains power nearby.

Data Telemetry & IoT

Data Telemetry & IoT

Remote sensor networks and telemetry equipment that need to report back reliably, day in day out, regardless of what's happening with the grid.

Water Quality Sensors

Water Quality Sensors

A growing use case for us — powering continuous water quality monitoring equipment at sites where running mains power isn't practical.

Gate Automation & CCTV

Gate Automation & CCTV

An established market that increasingly sees mass-produced solar kits — ours are built to keep performing through a New Zealand winter, not just a New Zealand summer.

Help Us Understand Your Specific Requirements

Complete as many fields as you can — partial answers are fine, and our team will follow up on anything critical that's missing. Site solar data is looked up by us based on the location you provide, so you don't need to source that yourself.

1. Deployment Profile

2. Load Profile

List every device the system needs to power. Run Hours/Day is how many hours it's actively drawing power — enter 24 for always-on, or fewer for scheduled/motion-triggered devices.

Device TypeQtyRated Power (W)VoltageRun Hours/Day

3. Solar Resource & Autonomy

System must be fully self-contained on battery + solar alone (no fuel cell backup)

Backup fuel cell (EFOY Pro) acceptable for winter / sustained shading events

4. Environmental Conditions

Enclosures are IP56 / IP65 rated for outdoor use by default.

5. Communications Load

Remote monitoring typically increases continuous power draw on the backhaul link — factor this into your load profile in Step 2.

What Goes Into a Solar Box Solution?

Most of what goes into a Solar Box is sourced and built to match your load and site — not a fixed catalogue item. DC/DC converters are the one component we typically hold as stock; everything else below is selected or sourced per project.

Solar Panels

Solar Panels

Sourced to match the wattage your system needs, with a pole-mounted frame. We don't stock a fixed panel range — panel size and quantity are calculated from your load, hours of operation and site's winter sun hours.

Solar Charge Controllers

Solar Charge Controllers

Selected to suit the panel wattage and battery chemistry, regulating charge to protect the battery bank and maximise the useful life of the system across the site's autonomy requirement.

Battery Banks

Battery Banks

Deep cycle AGM or LiFePO4 batteries, sized against your load current, hours of operation and required days of autonomy without sun.

DC/DC Converters

DC/DC Converters

Steps the battery bank voltage down (or up) to power any device in the box that won't run directly off the battery voltage. Our one typically-stocked component in this line-up.

Solar Cable & Connectors

Solar Cable & Connectors

Pre-terminated solar cable in 3m, 5m or 8m lengths with mating connectors, run between the panel and the enclosure.

Enclosures

Enclosures

IP65 or IP67 rated outdoor enclosures and lockable cabinets, sourced or built to your specification, with space for your equipment or pre-wired before shipping.

Frequently Asked Questions

Questions specific to Solar Box solutions. For general value-added questions, see the Value-Added Solutions overview.

The DC voltage(s) your equipment needs, the current it draws, how many hours a day it operates (typically 24/7), and how many days of autonomy without sun you want the system to withstand.

7–10 days if it's based on a design we've built before, or 2–3 weeks for a new design.

Yes. We can leave mounting space for you to fit your equipment on site, or receive your devices and install and pre-wire them into the enclosure on your behalf before it ships.

On repeat-configuration builds we can hold a buffer stock of finished units and scale production as your volumes grow, so a single supplier relationship covers your continuity of supply.
