This controller has 10 amperes.
这个控制器有10安培。
So, at most, we can connect two 50 W panels or one 100 W panel.
因此，我们最多可以连接两个50W的面板或一个100W的面板。
How do we figure that out?
我们怎么算出来的呢？
Suppose we have a controller of 10 amperes and the panels are usually 12 volts.
假设我们有一个10安培的控制器，面板通常是12伏。
So, we multiply our 12 volts by 10 amperes and get 120 W.
因此，我们用12伏的电压乘以10安培，得到120瓦。
It means that we can attach only 100, which is a little less, in order to have some power reserve.
这意味着我们可以只连接100，这有点少，以便有一些功率储备。
First, we connect the battery to the controller.
首先，我们将电池连接到控制器。
And only after we have connected the battery, we connect the solar panel.
只有在我们连接了电池之后，我们才连接太阳能电池板。
If you do the opposite, the power will come to the controller and there will be no outlet.
如果你反其道而行之，电源将进入控制器，而没有插座。
It may burn out.
它可能会烧毁。
That's why it is recommended to connect the battery first, I mean the wires leading to it, and then the wires leading to the panel.
这就是为什么建议先连接电池，我是说连接电池的电线，然后再连接面板的电线。
That's how it's done on almost all the yachts, the panels may not bend well, they may be stationary.
几乎所有的游艇都是这样做的，面板可能不好弯曲，它们可能是固定的。
But they will have the same two wires.
但它们会有相同的两根电线。
The only issue is that you need to attach the stationary panels somehow.
唯一的问题是，你需要以某种方式连接固定的面板。
There are different mounts.
有不同的安装方式。
On the roof of the boat, the topside.
在船顶上，在船顶上。
There are some racks.
有一些架子。
Some pulpit mounts.
一些船浆架。
You can attach the panel in many ways.
你可以用很多方式连接面板。
All the panels will have two wires - positive and negative that we connect here.
所有的面板都会有两条线--正极和负极，我们在这里连接。
We connect them using thick wires, the wire cross-section must be at least 2.5 millimeters.
我们用粗线连接它们，线的横截面必须至少是2.5毫米。
So, they must be quite thick.
因此，它们必须相当粗。
If you use thin wires, there will be huge energy losses.
如果你使用细线，会有巨大的能量损失。
Besides, the wires may get hot.
此外，电线可能会变热。
So, we connect all that stuff using only thick wires.
因此，我们只用粗线连接所有这些东西。
The longer the wire is, say, 20 metres, the bigger the wire cross-section should be.
电线越长，例如20米，电线的横截面就应该越大。
However, if our boat is small, and we don't need a long wire, say, up to 10 metres, 2.5 millimeters of the cross-section is quite enough.
但是，如果我们的船很小，而且我们不需要长的电线，比如说，不超过10米，2.5毫米的横截面就很足够了。
If you have any questions about connecting the panels, you can write to me directly and I will try to help you.
如果你有任何关于连接面板的问题，你可以直接写信给我，我将尽力帮助你。
