BATTERY CABLE CONNECTIONS

Up to 3 batteries are supported in parallel when connected to a single inverter, 4 batteries in parallel when connected to 2 inverters, or up to 5 batteries in parallel when connected to 3 inverters.

The maximum recommended number of paralleled 18kPV inverters is 6. If this approach is used, we recommend a ratio of 3 batteries per pack controlled by each 18kPV inverter. Separating packs is only recommended if each pack's average SOC is monitored over time and does not diverge by more than 10%. Common busbars are superior to separating battery packs but it may be difficult

The shirts run true to size and are very well made.
Color: Wine Red-polka Dots, Size: 3X-Large
I want the company COOFANDY and the customers who are considering buying these men's wrinkle free men's shirts for casual business wear, to know that the shirts are beautiful. The material is perfect, and they are made exceptionally well! One of the two shirts that I bought for my husband looks great on him. I had to buy one in a size 2x and one in a size 3x due to the reviews on Amazon's website, where so many of the reviewers stated that the size that they bought ran too small, while other reviewers said the shirt runs too large. My husband tried on the 2x, and it fit him perfectly, which was great because he always wears a 2x. The reason that I am returning them both is that these shirts are tuck-in shirts, and my husband only wears shirts that do not have to be tucked in, such as straight-bottom shirts. I showed him the picture of the shirt in the ad to prove that the models wore them out, not tucked in, but he said the style is wrong for wearing this shirt on the outside, and that he would not be able to wear it. I am so sorry, but I had to return them as he would not ever wear them. But I wanted you, COOFANDY, and your customers to know that the shirts are well worth the money and are just beautiful!

Perfect fit for my husband
Color: Army Green, Size: Large
Very thick but it's cool, comfortable, no shrinking when washed and no fading. Love this color and the quality of material for the price is top of the line. I will be ordering other colors. My husband really enjoys wearing this and it fits perfectly. Thank you for the excellent work.

Stylish, Well-Made Shirt—Just Might Need a Touch of Ironing
Color: Black-square, Size: 3X-Large
Why did you pick this product vs others?: My husband is a big fan of this shirt brand—they offer a great selection of styles, patterns, and fabrics, and the availability of a 3XL is a major win since it’s not easy to find that size. This particular shirt has a classy, lightweight feel with a subtle checkerboard texture that adds visual interest under the light. The fit is modern and breathable, perfect for summer wear. After washing it straight out of the package, the wrinkles from shipping didn’t fall out, so I wouldn’t call it truly wrinkle-resistant just yet. I’m hopeful that a single pass with the iron will help set it right. Overall, the shirt looks fantastic and the quality is impressive, especially for the price. Whether for a casual day or dressed up for an event, it’s a versatile choice—just be prepared to give it a little extra TLC after washing.
