My mum has a purewater factory, and with what you've listed above 15kva(3× 5/6kva hybrid inverter paralleled together) with 10kw of panels will do the job. Ours run mostly during the day. 15kwh of lithium battery is enough except your factory works at night. You can enlarge the battery bank depending on Night duty/Load. You can always have a gen backup but I doubt you will end up using it with what v listed above or we have 3-days of darkness

I want to clarify if you mean 3 pieces of 3phase machine rated 3kva each?
Single phase inverters are cheaper than 3 phase ones.
If I am to set this up I will rather go for 3 individual 48v 5kv-6kva inverters, each with a 7.2kw array of panels (minimum, preferably more) coupled with 15kw (48vx300amp) lithium battery bank. I will go for the high solar voltage CCs and possibly hybrid inverters to save costs. I will however parallel the batteries together, so that ,in case only one or two of the machines will be in use, then the other storage will not be idle.
A fourth 3.5-5kva inverter will be for pump and light. It will have its own panels but I will likely connect to the same battery bank to just complete the circuit but relying more on harvest from its panels to meet the power need.
As a minimum, a 7.5-10kva petrol gen should be available as backup, so that any of the water packaging machine could be switched over to generator if the need arises.
You can do your own initial assessment and calculations

This schematic might look strange but using solar/inverter for industrial use for years made me realize that a single 20kva inverter is like putting all my eggs in one basket.

Chief, this your question get as e be. It seems you want to go DIY without paying the price of reading up. If you want an installer to handle it for you then contact solid hands here that will deliver the job, otherwise all the information you need to set up your system is available here but you gats read up.... At worst, read to a certain extent so your questions or clarifications are more specific and can be answered easily.

Just an advice.

My experts in the House. I greet you all for all the enlightening may the Lord increase you.
Please i need a help. A client wants to setup an inverter and Solar system in his Pure water factory that will carry the following loads.
1. Sachet printing water packaging machine. According to the client the machine is 3pcs and each of the power input of the machine is 3kva X 3 and it will run for 8hrs daily.
2. 1hp pumping machine (Sumo) will go off once the tanks are full.

Still on this my professionals, any help? The man is eager
3. Lighting points for night

Please i need an advice on what system will work for this project perfectly.
1. Inverter capacity
2. Battery bank
3. PV capacity.
I will also like to learn all the calculations. Thanks in anticipation

Go get a Gen, I don't tink going solar for this is a wise investment because it's way much more expensive u will need atleast 20kva, the cost of inverter alone runs in millions

I have the guide. The information is worth trying than spending money with agents
I can sell it to you less price.
Inbox me if you want it
