Hamishon!

Hamishon offers a full range of reliable-power solutions — solar systems, power stations of every size, energy-storage batteries, inverters, petrol generators and diesel generators — matched to residential, commercial and industrial needs.

To choose the right bundle, start by working out which appliances have to stay on during an outage, how many hours of backup power you need, and whether you are able to install solar panels. If only the lights, the modem and the fridge are essential, a smaller bundle may well be enough; but for a television, an air conditioner, a water pump or any motor-driven equipment, both the higher power draw and the start-up surge of each device need to be checked. Selecting your use case and your goal in the store narrows the options down, and you can review the result with Hamishon's specialists before you buy.

Every system is installed and commissioned by Hamishon-approved suppliers and specialists, so both the quality of the work and its safety are fully guaranteed.

How long it takes depends on the capacity of the system, the condition of the roof or the site, the cable run, and whether the building's wiring needs to change. Once the equipment is ready, most home systems take one to three working days to install. The exact cost is quoted after a site survey, when the equipment, the mounting structure and the installation requirements have all been settled.

Every proposal is built around your budget, your consumption and your priorities, so you get the best performance and efficiency without paying for anything you do not need.

If you notice a drop in performance, an error, or an unexpected shutdown, submit a support request: the system is checked remotely first, and a site visit is arranged if one turns out to be needed. For your own safety, do not open the inverter or the battery, and do not change any wiring, without a specialist present.

The icons under each bundle are examples of what its power and capacity can keep running during an outage — they are not a limit on what you may use. Other appliances work too, as long as their combined simultaneous draw, their peak start-up power and how long you run them stay within the bundle's capacity. How much a bundle actually supports depends on what each device consumes, so for heavy loads such as an air conditioner, a water pump or motor-driven equipment it is worth checking more carefully before you buy.

It depends on the type of system and where it is installed. An off-grid system usually involves no grid-connection process at all, but a grid-tied system, or one that sells power back, has to be arranged with the electricity distribution company. In an apartment building you also need to clear the work with the owner or the building management before installing anything on the roof or in any other shared space.

For a typical home system with a battery of around 5 kWh, the battery is usually about 45 to 55 cm wide and 50 to 70 cm tall, and the inverter roughly 35 to 45 cm wide and 40 to 50 cm tall. In practice, part of a wall in a car park, a storeroom or a utility space is enough. You do also need to allow room for the cabling, for ventilation, and for access when the system is serviced.

A good spot gets direct sunlight for most of the day and is shaded as little as possible by buildings, trees or nearby equipment. A rooftop, a warehouse roof, open ground, a villa and — in some cases — a balcony can all work well; but the orientation and tilt of the installation, the strength of the structure and the space available all need to be checked before the work starts.

A power station stores electricity in a battery and runs silently, with no fumes and no fuel, which makes it a good fit for a home, an apartment, a clinic or an office. Some models can also be charged from a portable solar panel.
