If you have a modern version of Excel, you can download our sizing tool here and try out different combinations of load, batteries, panels etc.

Please see the pack content below for a breakdown of the components included in this kit.

Please note that these kits do not include installation.

For those not overly familiar with solar power, this kit can store around 2 Unit of electricity in the batteries.

This means that at night when there is no sun, you could watch a 300W TV for about 6 hours before the batteries went flat (300W x 6 hours = 1800Whrs = 1.8 Units of electricity)


you could run 20 x 5W LED globes for 20 hours (5W x 20 x20 hours = 2000Whrs = 1 Unit of electricity)


a 2000W kettle for an hour straight (2000W * 1 hours = 2000Whrs = 2 Unit of electricity) *Not sure why you would do that but who knows?*


any combination of the above that adds up to 2 Units.

During the day, the solar panels will first charge the batteries and after that will add whatever power they can produce, so you will be able to go longer depending on weather conditions.

If you need to do more than the above you need a bigger kit. Please contact us and we can do a quote for you.

questions Mbulelo on 05/05/2021

Does this system include the mounting rails?


Yes, the items this kit contains are itemised on this page. They include mounting structure for a tiled roof. If you have a different type of roof, just let us know and we will adapt the kit for your requirements.

questions Attie on 02/02/2021

Hi, Just want to confirm that I should switch my swimming pool and geyser off at the distribution board when using solar power only?


Hi Attie, manually switching on and off appliances and circuits as the power inputs change should not be part of the design of any system, so no, this is not the case.

Please remember that you need a licenced electrician to do any work or connection to your DB, who will structure the installation in such a way that the capabilities of the inverter are not exceeded.

questions SIMON HARPER on 21/11/2020

If I buy this 3kva off grid kit, can I substitute the 4 lead acid batteries for 1x Pylon 2.4 kwh 48v lithium battery. ? Is it compatible with that inverter?


Hi Simon. No, it's a 24V inverter and the US2000 is 48V. You could use the UPS2500 which is a 24V battery. 

You can get more details here:

questions Ralph on 11/07/2020

Hi, Can the batteries be connected in parallel to convert them to 24 volt.and is there any advantage?


Hi Ralph, this inverter is already a 24V battery inverter. You need to connect 2 x 12V batteries in series to get the required 24V.

Connecting batteries in parallel does not change the battery bank voltage.

questions Anton on 12/01/2020

Does this inverter allow power delivery during the day from solar only? In other words, not using battery/mains if the batteries are fully charged?


Hi Anton, yes it can run like this.

questions Dave on 11/12/2019

Would you able to replace the batteries for Pylontech batteries later on?


Hi Dave, yes, but only with the 24V Pylontech version.

questions Sydeny on 08/02/2019

Can one parallel connect the system eg if I buy 3 of these; can I connect them in parallel without issues of synchronisation


Hi Sydeny. Unfortunately only the 5kVa units can be paralleled. 

questions Wilson on 10/01/2019

Can this system also cater for a double door fridge?


Hi Wilson, yes it can.
