What is a Battery tied Solar PV System?
When the grid is off, you stay on
If you are looking for energy security during load shedding, plus savings on your electric bill for your residential home, office, company or commercial building then a battery-tied system with a hybrid inverter may be the solution you need.
THIS SYSTEM ALSO PROVIDES SAVINGS ON ELECTRICITYWith this system, your electric bill will come down substantially, thanks to the solar PV panels – the only drawback of this system is the initial cost; batteries and the necessary hybrid inverter can be pricey. If budget is a challenge, starting with a battery backup solution that is modular and fully expandable to solar PV in the future may be the smart way to go. Alternatively, if savings on your bill are most important to you, you can opt for a more cost effective grid-tied solar system.

Frequently Asked Questions
The percentage of your energy needs that the solar PV system will produce is dependent on the space and orientation of your roof and the local municipality’s generation limits for your property.
For a company, the business case for installing a solar system is good, having a low payback period (usually under 6 years) together with the falling costs of solar system equipment, rising electrical tariffs and tax incentives of a 100% tax-deductible depreciation allowance in the first year of installation. Your office, factory or commercial building will benefit from the savings and energy security that renewable solar power brings.
When the power goes off during load shedding, the hybrid inverter will continue to power some chosen “essential” loads from solar power (during the day) and batteries. Not all loads in the building will remain on. Adding more batteries and choosing a larger hybrid inverter will mean that more loads can run when the grid turns off – but this will increase the cost of the system.
Yes, thanks to the use of a hybrid inverter with batteries, your photovoltaic panels will continue to produce power during load shedding but will only feed the “essential” loads that are on the output of the hybrid inverter.
This depends on your municipality, as some do not have the capability for you to sell excess solar energy back to the grid. For the highest savings, we recommend maximising your personal use of the available solar power instead of prioritising exporting to the grid. In our experience as solar PV installers, we have not come across any municipality that will buy exported solar power at the same rate for which they sell their own power, it is usually less, resulting in lower savings if you export than if you used the solar power yourself.
To maximize your self-consumption, we recommend adding some battery capacity to your system, so that excess solar power gets stored in the batteries during the day and you can use this stored energy from the batteries in the evening and at night.
This doesn’t mean that it is a bad idea to have the option of exporting to the grid. In cases where your batteries are full and there is excess solar power, exporting to the grid would be the next best option to fully utilize the potential of your solar photovoltaic system. To export to the grid you will need a special meter installed by the local municipality. In Cape Town, a commercial business or company can apply for the city to install this meter free of charge.
Yes, generator integration is possible with this system, as many hybrid inverters have unique inputs for a generator, and others have built-in software that makes generator integration possible.
