Aircon peakpower vs solarcell capacity

[finnsk]

 

I am going to do a solarcell system on a budget, but got a problem.

 

I will make a solarcell system to run a 9000 btu air con, freezer and fridge on the sunny time of the day, I think a system which can make about 2000 watt and I will calculate the solarcell with an factor of 0,7 for shadows, dirt and incorrect solar angel etc,  and calcute 90 % on the inverter, so I think I must have solarcells at around max 3000 watt.

Because I am on a budget, I will try to get as little battery capacity as possible. I will make the system off grid with an automatic switch to turn on of the solar system/grid to the 9000 btu air con, freezer and fridge when the solar system is working.

 

Now the problem, its about the peak power when the air con is starting, it seems it needs up to 3-4000 watt a few seconds when it starts, I do not have this capacity on the solarcells, I was thinking about a battery 100 amp deep cycle, will that be able to support with enough peak power ?

 

I am no specialist only a stupid DIY, so hope somebody with better know how than me have time to help with an answer.

 

Thanks in advance

Are you off-grid or can you use PEA to top up your solar system?

 

I installed an energy monitor which shows me energy usage in real time. So I can switch on an air con and see how much power is being used.

 

I made a video about how it works

What about installing a heatpump? Would that help reduce the initial draw on power?

 

A study by the Florida Solar Energy Center found that high-efficiency heat pumps could reduce cooling energy consumption by up to 30% compared to conventional air conditioning systems. However, it is essential to choose a heat pump with a high seasonal energy efficiency ratio (SEER) for optimal performance in Florida's climate.
