bard v chatgpt

I asked both chat and bard the same question
"4*500w solar panel, 24w 3000 inverter, 24v 200ah battery, is this comaptable

first, the Bard responce was

No, the system is not compatible. The inverter power (24v 3000) is too high for the battery capacity (24v 200ah).
The maximum power that the inverter can handle is 3000 watts, but the battery can only store 200 amp-hours.
This means that the inverter will overload the battery and cause it to fail.


Second, chat
In summary, based on the information provided, the components seem to be compatible in terms of voltage and power.

So a yes from one and a no from other, Which is correct?

Compatibility is not a black and white concept. The question is too vague to be answered definitively.

Is ketchup compatible with eggs?

 

[intrepid]

yes but is ketchup always red?

Back in the old days with lead acid batteries there is a rule of thumb that you should have at least 100ah per 1000w of inverter output, although that was for 12v systems

AI's gonna suck up old knowledge and apply it to new technology. But that's what humans do anyway. Everybody don't forget to run your batteries all the way down once in a while so they don't get a memory!

AI isn't that smart. Still a dumb computer, it doesn't know real from garbage necessarily. So garbage in = garbage out.

A 3kW inverter is perfectly fine with 5kWh of batteries. Of course more kWh would supply max load longer.

2kW of PV panels is high for 5kWh of FLA batteries, may be acceptable for AGM batteries, should be OK for lithium batteries.

But fine for all if the system reduced power harvesting to maintain target battery current (e.g. 0.13C for FLA), and harvests more when loads also use power. Victron and Midnight have DC coupled equipment to do that. Any AIO should do it. AC coupled equipment should do it. Or, just undersize SCC to limit charge current, let the extra panels fill in during poor light conditions. Orient PV panels multiple directions.

I think AI mostly regurgitates what people have written, maybe said. Perhaps it can check their math. I'll be more impressed when it can apply engineering principles (not just plug values into equations.)

I posed same question to the updated Bard and now it responds with:

Yes, your setup is generally compatible but there are a few potential limitations to be aware of:


Compatibility:

• Solar panels: 4 x 500W solar panels connected in parallel provide a total capacity of 2000W. This is sufficient for your 3000W inverter, although it may not operate at its full capacity all the time.
• Inverter: A 3000W inverter is capable of handling the combined output of the solar panels. However, it's important to check the continuous power rating of the inverter. If it's lower than 2000W, it may overload and shut down when the solar panels are generating maximum power.
• Battery: A 24V 200Ah battery provides a capacity of 4800Wh. This is enough to store a significant amount of solar energy, but it may not be enough to power your appliances for an entire day if you have high energy consumption.

Limitations:

• Shading: If any of your solar panels are shaded for a significant portion of the day, it will reduce the overall power output of the system.
• Weather: Solar energy production is dependent on sunlight. On cloudy or rainy days, your system may not generate enough power to meet your needs.
• Battery capacity: The battery capacity may not be sufficient to power your appliances for an extended period,especially if you use them frequently or draw a lot of power.

Here are some things you can do to optimize your system:

• Clean your solar panels regularly to remove dust and debris.
• Ensure your solar panels are positioned in a location with maximum sunlight exposure.
• Consider adding more batteries if you need additional storage capacity.
• Use energy-efficient appliances to reduce your overall power consumption.
• Monitor your system performance to identify any potential issues.

Overall, your system is compatible and has the potential to provide you with clean and renewable energy. However, it's important to be aware of the limitations and take steps to optimize your system for maximum performance.
