What are SunSynk Inverters?
SunSynk Inverters convert DC Power (Direct Current Power) from the Solar Panel Array and/or the Batteries into AC Power (Alternating Current Power) for your premises.
AC Power is the type of electricity provided by the Grid (when it is working).
In an off grid Solar Energy Power System, the Inverter replaces the Grid and becomes the supplier of the AC Electricity to your premises.
Whilst the sun is shining, the Solar Panels produce the DC power that is converted by the Inverter into usable AC electricity to power the appliances in your premises.
After first supplying the power needs of your premises, the Inverter then directs any excess power into your Batteries where the energy can be stored.
An example scenario:
The Solar Panel Array is producing 10 kW of power; your premises is requiring 5 kW at that specific time and the batteries SOC (State of Charge) is less than 100%.
The Inverter supplies the 5 kW to the premises and directs the excess 5 kW into the batteries until they are fully charged.
During the day time, if the Batteries are fully charged then the Inverter only takes what it needs from the Solar Power input to supply the premises which in this example scenario is 5 kW. The extra 5 kW is not used until the premises draws more than 5 kW.
However, at night (with no power from the Solar Panels) or on very cloudy days (with not enough power from the Solar Panels), the DC power has to be supplied (and/or supplemented) by the Batteries to the Inverter which then supplies AC power to your premises.
Other configuration options are hybrid Inverter/Grid connections:
In this scenario, the system in inter-connected with Eskom (the Grid) and Eskom provides the shortfall if the Sun is not providing enough power and the batteries run too low OR at night when there is no power from the Sun and the batteries run too low.
One can set the batteries to stop providing power at various levels. For example one can set the system so that when the Batteries reach 50% then Eskom kicks in and provides the power to the premises. This scenario usually happens at night especially if one is using heaters.
The system is set so that Eskom only supplies the premises either when the Sun is not providing enough power during the daytime or during the night time when the batteries have reached a certain preset level (e.g. 50%). The system is set so that Eskom does not charge the batteries.
The batteries will only charge up again when the Solar Panel Array produces enough power to cover the needs of the premises and then whatever excess power is available is used to charge the batteries.
In this example (Batteries set to stop providing power at 50% capacity), the moment the Batteries start charging (in other words the power from the Solar Panel Array is more than the demand from the premises and the excess is directed into the batteries, then the system disconnects from Eskom.
Although this Hybrid Solar/Eskom setup may be a cheaper option initially than buying extra Batteries… keep in mind that Eskom intends to or is already charging a surcharge for premises that only use Eskom as a backup… so the economics may still be better to buy Batteries in the long run.

Bright Future Solar SunSynk Inverter range:
There are many brands of Inverters out there to choose from. Some may be more or less on par with SunSynk and some are downright shoddy.
Keep in mind that the specifications for most brands of inverters will look good on paper but not all are built to the same high electronic engineering specifications.
Rather than confuse you with a myriad of Inverter brands… which may well be six of one and half a dozen of the other… or perhaps 8 of one and 4 of the other… Bright Future Solar exclusively offers SunSynk Inverters of various output power capacities.
SunSynk Inverters are robustly built, a joy to set up and operate and are highly respected in the Solar industry worldwide.
SunSynk Inverters have a 10 year warranty. Conditions apply.
Bright Future Solar SunSynk Inverter range includes:
Single Phase:
Inverters Only (batteries are separate components): 5 kW, 8 kW, 10 kW, 16 kW
Combination Inverters/Batteries: PowerLynx XL – 5.5 kW Inverter and 5.12 kWh Battery in one unit
Three Phase: 50 kW
What Inverter output capacity size to choose for your premises:
Inverters are available in a range of maximum Power output capacities measured in kilowatts.
For example 5 kW, 8 kW, 10 kW, 16 kW etc.
For most residential homes we recommend at least an 8 kW Inverter output capacity size and ideally the 16 kW Inverter.
All appliances e.g. T.V., Lights, Fridge, Freezer, Geyser, etc use power measured in Watts.
A T.V./Decoder may use around 250 Watts; a Fridge may use 200 Watts; a Geyser may use 2000 to 3000 Watts (2 to 3 kW);
Typically, a normal residential premises may be able to operate on an 8 kW Inverter but will require very careful appliance power management.
For normal 4 bedroomed households the ultimate peace-of-mind with minimal appliance power management will come with a 16 kW Inverter.
With a 16 KW Inverter, practically no power management of appliances will be required and one can safely add on big power consumers, for example air-conditioners, additional geysers, additional fridges and freezers, etc. without concern.
Up to 16 Inverters (of the same power output capacity) can also be paralleled to increase the maximum power output capacity.
For example 2 x 16 kW Inverters will have a collective maximum power output capacity of 32 kW.
For one’s home, one can go smaller than 8 kW but then it may result in one’s life revolving around ‘managing’ the power output rather than enjoying the bliss of energy independence.
For example, for a small residence, a 5 kW Inverter will easily be able to power your T.V. & decoder (+- 250 Watts), Lights (+- 100 Watts), Fridge (+- 200 Watts), Freezer (+- 200 Watts), Washing machine (+- 300 Watts unheated), Microwave (+- 1000 Watts) & Kettle (+- 2000 watts).
Using a 5 kW Inverter will however require hands-on management to power your geyser (+- 3000 watts) for example.
In such a case one would have to switch the geyser off before operating the kettle or the microwave. Or whilst using the microwave it may be pushing the limits of the system to use the kettle, etc — You get the idea : )
Another factor to take into account is the maximum number of Solar panels that can be connected to the Inverter. Bigger Inverters can take bigger Solar Panel power inputs.
For example: 5 kW SunSynk Inverters can take 6000 Watts of Panel Power (11 x 545 Watt Panels); an 8 kW Inverter can take 10400 Watts (19 x 545 Watt Panels) and 16 kW SunSynk Inverters can take 20800 Watts (38 x 545 Watt Panels) of Panel Power.
Why is this important?
Panels are by far the cheapest components of your Solar Energy Power System (Inverter, Batteries, Panels).
The maximum output power of the panels is referring to the peak rated power of the panels. The peak power will only be produced on optimum sunny Summer days with the sun directly overhead.
On cloudy days however the output can reduce down to as little as 10% of max output — especially on rainy heavily clouded days, although on moderately cloudy days the output may still be as high as 40 to 60%.
Either way, 10% and 60% of a higher maximum output is still higher than a much lower maximum output so it makes sense to maximise the number of panels depending on the available space and your budget.
Also keep in mind that Solar panels do not need direct sunlight in order to operate. So long as there is daylight (even on very cold Winter days) they will produce power somewhere in the range of 10% to 100%.

Thus, taking all of this into account…
Rather get the biggest Inverter your budget can afford.
One can always add on more batteries (the most expensive Solar Energy Power System component) at a later stage.
Our motto when it comes the maximum output power capacity of Inverters, the storage capacity of Batteries and the output power capacity of Panels is:
Bigger is BETTER!!! More is BLISS!!
