More info

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.

Our 3kW Off Grid kit consists of:

  • 1 x 3kVA Solar Hybrid Inverter 

  • 2 x 325W JA Solar Monocrystalline Modules 

  • 2 x 100Ah 12V AGM Sealed Solar Batteries 

  • 50m x 4.0mm Solar Cable

  • 2m x 25mm battery cable & lugs

  • KETO Battery disconnector wit 160A fuses

  • KDC Switcher/Disconnector for the panels

  • MC4 Connector kit

  • Mounting Clamps and channel (2 x 2m)

Please note that these kits do not include installation.

For those not overly familiar with solar power, this kit can store around 1 Unit of electricity in the batteries.

This means that at night when there is no sun, you could watch a 300W TV for about 3 hours before the batteries went flat (300W x 3 hours = 900Whrs = 0.9 Units of electricity)


you could run 20 x 5W LED globes for 10 hours (5W x 20 x10 hours = 1000Whrs = 1 Unit of electricity)


a 2000W kettle for half an hour straight (2000W * 0.5 hours = 1000Whrs = 1 Unit of electricity) *Not sure why you would do that but who knows?*


any combination of the above that adds up to 1 Unit.

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 Kobus on 25/02/2021

Good Morning , can this system be set up for/or Grid tie (priority Solar , then Eskom , then Battery when Load shedding.


Hi Kobus. No, you can have either Solar, battery, utility or Utility, solar, battery

questions Henry on 07/02/2021

HI, can the system set that it mainly use the solar/battery power and only use grid power if really needed


Hi Henry, yes, within the limits of the system output.

questions Elliot Hall on 09/10/2020

Hi, Im wanting to run my pool motor on solar. Would this system work. Its a .75kw motor.


Hi Elliot. No, this isn't a good application for this kit. The inverter is big enough but there is only 600W worth of panels, and the batteries would only last an hour and a half under no sun conditions. 

If you want to save money on your pool pump, the best solution is a straight grid-tie solution like this one here:

questions James Anderson on 01/08/2020

Hi there, I want to use this to run a satelite wifi system, as a semi grid tie system, in that during any given day we have power cuts of +-18hrs. So during that time I want this system to run the wifi( which pulls less than 30W) but is there an option to keep the inverter plugged into mains so that when the mains power comes back on it will then charge the batteries? My apologies if this is a stupid question but I,m very new to this solar tech


Hi James, yes  you can plug the mains into the inverter and set it to recharge the batteries automatically when grid power returns.

questions Ashley  on 30/07/2020

Good day. Is it 1 x unit of usage per battery, or 1 x unit per 2 batteries?


Hi Ashley, at the battery manufacturers recommended depth of discharge of 50%, each battery will offer you approximately half a unit. So it's 1 unit of storage capacity for the 2-battery bank.

questions mark on 23/07/2020

What is the difference between this off-grid kit and a hybrid kit as it seems this can also connect to mains electricity via a hybrid inverter?


Hi Mark. A hybrid inverter is a combination of a battery inverter (like this one - they still have grid inputs) and a grid-tie inverter which can reverse power through your meter.

You can have a look at the different types of solar power technologies that are in use here:

questions Sam on 10/07/2020

What would the impact of double the battery capacity be? Would the solar panels need to be upgraded or increased in quantity?


Hi Sam, yes you would have to double the panels and look at the Off-grid Solar Kit - 3kVA Plus

questions Ralph on 23/06/2020

Hi, I want a system for a small 2 bed cottage off grid. Basically a fridge freezer, A++, LED lights x 5, a outside LED spot light , A small washing machine during the day. and maybe run small power tools during the day. Will this manage this?


Hi Ralph, Probably not. You will need to complete either our solar sizing spreadsheet or our info form in order to properly calculate your requirements.

Unfortunately we cannot accurately size a system for "a few small power tools". We need to know the power draw of each and the expected daily use.

You can find the spreadsheet and/or form here:

questions Pieter Bester on 05/02/2020

Thank you for excellent website.I would like to run the following during load shedding. 1tv 1 decoder 1 fan 2to 3 lights and 1 more plug for a charger.Will this 3kw kit be sufficient,and the cost for installation. Thank you.


Hi Pieter, thanks. This kit would back up those items for around three hours at a battery DOD of 50% which is the recommended depth of discharge.

questions jay on 18/01/2020

Good day i am keen on this package what will cost be to add another 2 batteries and how many more additional 5w leds can i power up,


Hi Jay, you won't be able to run additional batteries in a purely off grid mode, as the panels will not be able to charge the batteries fully. You would need to have it connected to the mains as well.

The inverter will determine the number of appliances you can run simultaneously. The batteries will determine how long you can run for.

questions Mags on 14/01/2020

I am looking for a basic system that can power 5 ceiling fan lights and 10 other lights, electric bar fridge and TV for 1 hour or so. Off grid.


Hi Mags

This kit will be great for this.
