HOW DOES THE SMART POWER SYSTEM (SPS) WORK?
The SPS can be used straight out of the box. It simply plugs into a wall socket using the supplied cable. Your appliances are then plugged into the machine. The SPS stands between the wall socket and your appliances monitoring and smoothing out potentially damaging surges and spikes in the utility power.
At the same time it maintains charge in its batteries. In the event of a power failure the SPS instantly switches to battery power giving uninterrupted power to your appliances.
An inverter inside the SPS converts direct battery current (DC) to higher voltage alternating current (AC). This allows the battery-based system to run conventional electronic equipment.
WHAT EQUIPMENT CAN I RUN?
Anything that normally plugs into a wall socket and is within the power rating of the SPS.
SPS-500 - 500W
SPS-600 - 600W
SPS-1000 - 1000W
Several devices can be connected at the same time using a multi plug extension.
The power consumption of a device can be found on its specification plate or from the manufacturer’s literature.
Some appliances, especially induction motors, need a surge of power on start up. The SPS is able to manage these brief surges at up to twice its power rating.
(Detailed specifications of each SPS machine are available on the products dropdown menu)
WHAT CAN’T I RUN?
The SPS will not run power hungry devices like cookers, kettles or geysers.
HOW LONG WILL THE SPS RUN FOR?
The SPS can keep appliances running for several hours. How many hours is dependent on load and battery capacity. As you increase the load (plug in more equipment) your runtime will decrease.
Examples of run time using average appliance consumption....
SPS-500 (1 x 100AH GEL battery) would run a modern 46” flat screen lcd TV (100W), DSTV decoder (50W), laptop (50W) and 20W low energy lamp for 3-4 hours.
SPS-600 (1 x 100AH GEL battery) would have the same run time as above but has the ability to run for much longer if a solar panel is attached.
SPS-1000 (2 x 100AH GEL batteries) would run a complete computer system (300W), 46” flat screen lcd Tv (100W), decoder (50W), two 20W lamps (40W), inkjet printer (50W), and phone charger for 3-4 hours. OR an A+ fridge/freezer for 18-24 hours.
Check power consumption of your individual devices.
Heavier loads decrease run times.
Lighter loads increase run times.
Connecting a solar panel can dramatically increase run times.
WHAT TYPE OF BATTERY DOES THE SPS USE?
The battery is an important component of the SPS. It will determine how long the system will run, how deep you can drain the battery and how many times you can discharge it (cycle life).
The SPS can use any of the following deep cycle battery types -
Wet Cell batteries. These are the least expensive but have the shortest life expectancy.
AGM batteries (Absorbed Glass Mat). These are the type most commonly used in inverter systems. They are best if recharged before the battery drops below the 50 percent discharge rate.
GEL batteries. These cost more but have a cycle life twice that of AGM or Wet Cell. They are rugged, safe, spill proof and leak proof with the capability to be deeply discharged and to repeatedly accept recharging. Gel batteries, because of their longer life, offer the lowest overall cost per cycle.
We recommend using Gel batteries for their enhanced performance. The SPS can, however, use the other battery types.
The Gel batteries we supply are rated 100AH 10Hr. This is the measure of energy the battery can store and deliver to a load expressed in Ampere Hours (AH) over a given period of time, in this case 10 hours (10Hr).
(Detailed specifications available on the products dropdown menu).
CAN I BUY THE SPS WITHOUT BATTERIES?
Yes. In case you already have batteries, or want to source them elsewhere, we sell the SPS both with and without batteries. Fitting your own batteries into the SPS is simple, with full instructions provided.
If you buy the SPS with our GEL batteries they are fitted and connected before despatch. The machine will arrive ready to switch on and use.
WHAT KIND OF CHARGER DOES THE SPS USE?
An automatic 3 stage charger specifically designed to protect deep cycle batteries against over-charge, over-discharge and accidental depletion. The charger delivers constant current bulk charging followed by constant voltage absorption charging followed by constant voltage float charging.
The SPS-600 and SPS-1000 have additional PWM solar chargers built in. This means they can also charge batteries and run appliances via a solar panel.
WHAT IS PURE SINE WAVE?
This is the type of electricity the SPS produces. Pure Sine Wave, often referred to as “clean” electricity, is the same as that supplied by the utility grid. It is the type all electronic devices are designed to use where the voltage rises and falls with a smoothly changing phase angle. Pure sine wave power ensures maximum compatibility with sensitive electronics like computers, network devices and audio visual equipment. It allows your equipment to run cooler, last longer and operate without the malfunctions or reduced performance caused by substandard power. Many devices require pure sine wave to run properly, including variable-speed equipment and computers with active PFC power supplies.
Modified sine wave inverters produce a voltage that rises and falls abruptly in a staggered waveform. They are simpler and cheaper to manufacture but can cause electrical interference. Some electronics will not work at all with a modified sine wave - also called square or simulated sine wave.
DOES THE SPS NEED REGULAR MAINTENANCE?
No. The SPS has no moving parts and as such needs no maintenance. If it is stored away and not used for long periods of time the only thing we recommend is to plug in once every 6-12 months to fully charge the battery.
HOW DOES THE SOLAR FUNCTION WORK?
The SPS-600 and SPS-1000 have a solar controller built into the electronics. This solar function can be used independently or alongside AC mains power to maintain charge in the batteries and run appliances. Standard MC4 sockets inside the SPS allow for simple two cable connection to a solar panel. The solar controller then regulates current from the solar panel allowing the SPS to provide electricity in more remote, off-grid situations like smallholdings, holiday homes or camping or in mains-connected locations where the power may go off for more than a few hours.
If the SPS is plugged into mains electricity and a solar panel at the same time the central processing unit (CPU) will give preference to solar power when it is available.
A solar panel is not needed to run the SPS but can be connected at any time.
The SPS-500 does not have the solar function.

WHERE CAN I USE THE SPS?
Anywhere you need power.
The SPS is mounted on wheels. With the inverter, charger, CPU, solar controller and batteries all connected inside one cabinet the unit can easily be moved from room to room. Or extension cables can be used to take power to where you need it.
The SPS can also be loaded into a vehicle to provide power off site.
On camping trips you can enjoy the benefits of electricity, even in the most remote locations. No noisy generator. No messy petrol or diesel. Plug in lights each evening. Power your fridge. Run a cooling fan, laptop and phones. For longer trips the SPS can be recharged each day with a solar panel.
WHICH SPS SHOULD I BUY?
To help you decide, the main SPS differences are listed below.
SPS-500 is the smallest machine with space for one 100Ah battery inside. This would run a 250Watt load for approx. 3 hours.
If you just want to power small loads like an lcd TV, DSTV, laptop and a couple of lamps then this is ideal.
SPS-600 has space for one 100Ah battery inside but can also use solar power.
If you want to run slightly larger loads or to connect solar panels at any time in the future, choose this model.
SPS-1000 must have two batteries installed as it runs on a more efficient 24V system with 2 x 12V batteries wired in series. It can also use solar power.
If you want a longer run time, to be able to power larger loads and the option to connect to solar, this is a good choice.
ARE LARGER SPS MACHINES AVAILABLE?
The SPS-1000 is the largest machine in the range. It is not designed to run an entire household, but is a cost effective way to power essential appliances like fridges, lights, computers etc.
To run bigger loads, like an oven, stove or geyser, requires a much larger inverter and charger and, more importantly in terms of cost, a far greater number of batteries.
