AC VS. DC Coupled Solar Batteries: Which is the Better Choice?

In this video, Larry and Warren discuss AC-coupled and DC-coupled solar battery systems. If you're considering solar panels and batteries for your home or business, understanding how the two systems are connected is crucial. The two main integration methods are alternating (AC) coupling and direct (DC) coupling.

Learn how AC-coupled and DC-coupled solar batteries work and the pros/cons of both methods.

Accurate and well informed video! Good job in giving an unbiased viewpoint!

Very good video! Thank you for giving well informed, balanced insight! I do believe and am seeing on the SolarEdge Home Battery 400V Warranty that the cycle warranty is unlimited. Thanks again gentlemen.

While I love Enphase's system, I have decided to go with a string inverter This is because I want the heart of the system - the inverter - to be out of the elements. My time in the Army taught me that electronics don't like extreme cold, really don't like the heat, and hate water. I know that micro inverters are designed to be outside, but I'm beating that I significantly increase the chance of the inverter making it 25 years when it's in my garage and not on the roof.

I am having a system with Enphase micro inverts but I want to use a DC only battery

Hello Everyone, I have a StorEdge system which works very well. The specifications on my system is as followed( SE7600A-USS 400VDC system array is 4.38KW system). I have an LG Chem battery (400VDC). This system is expandable if I need to do so. So far it runs the whole house just fine including the AC 14 seer Unit just fine. But my battery 9.8 KWh battery is too small. I would like to increase my battery system to 40KWh capacity and increase my array by 4x 400watt panel. Due to the high voltage 350-450 VDC by the array. I would need a charge controller to charge or a board to reduce voltage to 150 VDC or a board that will charge and discharge the batteries safely. That way I can keep it on VDC to the Inverter. Does anyone have any ideas?

Your solar calculator requires everyone to reveal their contact information and you probably should have mentioned that in the video. On the other hand, you didn’t say it was free either.
