3kw Solar System Design | 3kw 24v Solar system Design

1. Copex CP 3024 Inverter: 24v - 3kw pure shine wave & charger. Its work with solar and main electric line. It has built-in 30A (variable) charger. When main line available, it works like as IPS.

2. Charge controller: Deutche power 60A- 12v/24v/48v MPPT charge controller.

Firstly connect the batteries to the mppt's and inverter input. Grounding wire is needed.
Secondly connect the solar panels.
Before all of these, specify to the users the size of the dc cables in mm² per lenght for MC4 cables and battery connection. Use a 24v dc wire calculator to estimate the voltage drop and heat generated in the wires so they will know what dc battery cables to use.
Don't forget to add the spark detection automatic breaker to the solar panels circuit.
Don't forget about AFDD, RCBOS and dc switches and fuses needed on all sides of the circuit.
You can't just work with basical electrical wiring generated on pc. You advanced skills to properly design a circuit. Not all MPPTs can work in parallel. Only some of them.
You need safety.
Your circuit doesn't not comply to any safety and regulations worldwide.
You have no cabling sizing, no breakers, no fuse block, no solar junction box, no minimum battery size AH explained for the amount of solar power posted in this video.
The total battery power must be 6 times bigger than the peak power of the solar peak input.
For a 3kw solar system you need 18kwh of AGM deep cycle batteries or 10kwh of Lifepo4 24v.

Except you are using pwm controllers. The mppt controller are designed to be connected in series until you get to the Max Voc.

how much AH total for the battery for this setup? thanks.
