Hi Colin. If you play about with the numbers you can see that you''ll need 140Ah of battery capacity at 12V to get 4 hours runtime for a 250W load. If you like, I have a very old ex demo 300W sine wave inverter your club is welcome to. I''d attach two 12V 100Ah batteries in parallel to this and that will run the lights for over 6 hours.
应该摒弃逆变器！ 效率只有70%左右,乘上你电源适配器不超过80%的效率,这么两次折腾,效率接近50%。 最佳方案是：用三组6V电瓶,电压18V多一些,淘宝买一根带圆 …

电源的额定功率是输出功率。所以输出500w你就能用500w（如果没有虚标）。 你看看电源铭牌,上面有各路输出的最大额定功率。如果要装机,建议参考+12v输出,这一路才是最重要的（当然,好的电源+12v输出只会比电源的额定功率小一点）。

如果近似的认为12v左右就是12v,9v左右就是9v,那锂电池是可以做到的,毕竟一个也就3v左右,串起来就行了。但是它这么做,你给他买单吗？ 大部分都是12v为单位,那是因为整个社会环境就是12V,搞个9V是要反吗,会被按到地上摩擦还不知道为啥的！

所以导致很多大功率的电源只能设计成双路12V输出,甚至四路12V输出,即便Intel之后改进了ATX标准,不再将限制12V电流限制为18A,但是还有厂家钻了标准规范的漏洞,继续以ATX2.2标准生产大功率电源。 双路12V供电下的实际可用功耗该怎么计算呢？
