谢谢分享!你的夜灯是12v AC or DC?如果是AC的,那个黑色的是12v DC 的吧,是要先转AC吗?100多个灯只要200w?那电流不大,最多20A。如果有1000w,电流要快80A,电线是不是要用80A的?那可不便宜。所以我看Youtuber建议用24v or48v,减少电流。你的setup需要fuse吗?是不是那个power socket就有?
还有,电池 (energy storage devices)的tax credit好像是要3kwh以上才算,不知道理解的对不对
What expenses are included?
The following expenses are included:
Solar PV panels or PV cells (including those used to power an attic fan, but not the fan itself)
Contractor labor costs for onsite preparation, assembly, or original installation, including permitting fees, inspection costs, and developer fees
Balance-of-system equipment, including wiring, inverters, and mounting equipment
Energy storage devices that have a capacity rating of 3 kilowatt-hours (kWh) or greater (for systems installed after December 31, 2022). If the storage is installed in a subsequent tax year to when the solar energy system is installed it is still eligible, however, the energy storage devices are still subject to the installation date requirements). Note: A private letter ruling may not be relied on as precedent by other taxpayers.
Sales taxes on eligible expenses

这些灯都是市面上普通12v Low Voltage Landscape Lighting. 就是12v AC, 但 12V DC 一样能亮。 光线还更稳定。 没有flickering. 安装也特别简单。我主线是10Ga的low voltage wiring, 出来后是分线到14Ga再接灯。 电流没有具体測, 估算是5-10a, 每组灯不太一样。 但不会到80a那么多。
