Solar Day and Night

Your home power demands fluctuate during the day and night. Excess power produced during the day is stored in a battery for power demands at night. This makes your solar power available to you when you need it, even at night.

Home Power Demands
How it Works:Our Home Solar installation consists of a solar array, an MPPT charge controller, a Hybrid UPS inverter and a battery bank to store all the solar energy yield for use at a later time.
  • Solar Array
Installed on your roof, the solar panels convert Sunlight into electricity. Typically solar panels are ranging between 250-310 Watts.
  • Solar Charge Controller
A Victron MPPT solar charge controller takes care of the right amount of DC solar energy produced, alternatively a Fronius single phase grid Inverter with build in MPPT can be used to produce AC power for direct use and/or feed back into the grid.
  • Battery Bank
This is your storage of excess sunlight that you did not use during the day or power from the grid when it’s available.
  • The Hybrid UPS Inverter
Converts the DC electricity from solar panels or the battery into AC current used by your home appliances, lights and other devices.
  • The Grid Tied Solar Inverter
Works without a battery bank and usually includes one or several build in MPP tracker. These transformerless inverters can be used for self consumption or feed back power into the national grid. Fronius grid tied inverters are available as string inverters, single and split phase from 3KW to 27KW.

Hybrid Grid System

In Zimbabwe, a hybrid grid connect system means your property is still connected to the mains power supply with a battery bank for power cuts. A hybrid grid connect installation ensures you have the electricity you need, whenever you need it – automatically and regardless of conditions. This system also works in remote areas where there is no mains supply.

Let’s Prioritize solar yield in a DC-coupled system to ensure fast financial return on your Investment by cutting down on your ZESA bill

System:Victron MultiPlus/Quattro, powered by the grid, solar charger, solar batteries, AC loads and optionally also DC loads.

Solution:Older Victron Inverters use the virtual switch (VS) to enable ignore the AC input, based on battery voltage, and optionally also on electrical power being drawn by the AC loads. Newer Victron Inverters use either the VS or the new ESS (Energy Storage System) assistant. It will only charge the batteries from the grid if needed to preserve battery health, and leave the rest for the solar chargers. The mechanism preserving battery health is called sustain. This assistant has more relevant optional features: • load shedding • feeding back dc-coupled solar power to the grid • periodic equalisation/destratification charge Both solutions aim at making full use of solar power generated by your system while keeping your batteries fully charged for possible night grid failures or load shedding. Once legal and technically possible in Zimbabwe, Victron Inverters through Assistants and smart build in software are able and prepared to feed power back into the grid which will ideally generate an income for you on excess solar power produced by your array.

Victron and Fronius have partnered to integrate each other’s systems by incorporating software.Their products can seamlessly be added to grid tied or off grid solar systems, allowing the most advanced and efficient interaction with incredible flexibility to suit any of your needs. Perfect Symbiosis.

Understanding Watts: A Quick Guide

It’s important to understand how your power is used
O

Watts are Like Kms-per-Hour

Let’s start with that 40-watt lightbulb. Power is a measure of the rate at which energy flows, and in electrical systems it is measured in watts (W). Watts are basically the kilometers-per-hour measurement of the electrical world, they tell you how fast the electrons are speeding down the road. For those who are keeping track, one watt is equivalent to electricity flowing at a rate of one joule per second in the metric system, which is also equivalent to 3.4 Btus per hour. A 40-watt lightbulb will consume electricity at a rate of 40 watts.

kWh are like the Km you have travelled

When you get your ZESA bill, the electricity you’ve used is measured in kilowatt-hours (kWh). While a watt is a measure of power, a kWh is a measure of energy. If you run a 40-watt lightbulb for one hour, you’ve used 40 watt-hours, or 0.04 kilowatt-hours, since a kWh is 1,000 watt-hours. In other words, 0.04 kWh is the amount of energy you need to run a lightbulb for an hour. If you travel 100 km in a car, you could drive at 10km/h or 100 km/h, the difference is the arrival time. Energy is similar. The more watts used, the quicker you will be using Kilowatt hours.

Your own Power Station

Now you understand the basics, Imagine you have your own power station (A Madison Hybrid Solar System), and every day you get a delivery of power (Sunshine.) You can now run your appliances using the free energy you get every day. Pretty soon your power station will pay for itself. You are less reliant on the grid and are helping reduce the burden on the current infrastructure. So not only do you get a sustainable power source that reduces emissions, you get the convenience of a system that is silent and seamless. That’s priceless!

Ways to Reduce Your Power Consumption at Home

Gas Hob

Cook On Gas

The electric hob and oven use electric elements that consume large amount of electricity in order to cook your food. Many Zimbabweans are turning to LPG as a fuel for cooking. The savings are beneficial and many find the changeover easy to do. When you decide to get a solar system from Madison, we recommend this change to all our customers as it reduces the size of the system you need to buy to power your home.
Whistling Kettle

Goodbye Electric Kettle

An electric kettle is a huge power hog. The high wattage of electric kettle elements is a huge drain on your inverter battery and is easily replaced with a whistling kettle on your gas hob. Often overlooked in the home, the electric kettle is a very easy to live without replacement with a whistling kettle will save you power bills and extend the capacity of your hybrid solar system to power other appliances.
Thermo Flask

Hello Flask

Invented in 1892, the vacuum flask keeps whatever you put in it hotter or cooler for longer. In an energy conscious home, keeping the excess hot water in a flask for that cup of tea a little later. It’s a satisfying feeling to have saved that gas, as well as a huge time saver. It’s highly likely you have this household item already so there is no outlay, making it easy to save energy today.
LED Light Bulb

LED Bulbs

LED light bulbs are more affordable than ever. Easily halve your consumption by making the transition. LED is far superior to energy saving bulbs in service life and watts used. Don’t wait another moment. Replace any blown bulbs to the LED equivalent. If you are looking at one of our systems, then this is an excellent place to start. We advise all our clients go LED to reduce the size of the inverter needed.
