Changes

There are five [SUNGOLDPOWER 24V Monocrystalline 200W Solar Panels](https://sungoldpower.com/collections/monocrystalline-solar-panel/products/200-watt-monocrystalline-solar-panel#specification_1)(62.2 x 31.8 x 1.4 inches) that are connected in parallel, which keeps their voltage at 24 V and adds up their amperage. On a sunny day, they output up to 500 W to the [SolarEpic 4125BN MPPT Solar Charge Controller](https://solarepic.com/products/solarepic-mppt-40a-solar-charge-controller-150v-pv-input-tracer-4215bn?variant=12497866457137). The charge controller is rated for 40 A.

_Our latitude is 36.4037°_.

The [[Micro Hydro Turbine]] system outputs around 60-110 W all day long. We currently don't have any accurate information on its original efficiency, head, or other characteristics. Please update this section and the micro-hydro page if you know more.

The micro hydro input, the small solar panel

The current inverter's maximum continuous battery charger input is 3600VA. It's maximum alternating current (AC) output overcurrent protection is 35 A at 110 V.

Most of the reported lead acid battery explosions are caused by charging a flooded automotive battery outside the car with an unregulated battery charger. In this case the battery can be left on charge for a long time, and the unregulated charger can run it out of water. Chargers that are designed for battery tending or maintenance , as well as most of the PowerStream lead acid chargers can be left on the battery forever without causing them to gas. Simple, old fashioned, or unregulated transformer chargers should not be left on the battery after it is charged.[^powerstream]

One should refrain from adding new batteries to an already used set as it wears down the old batteries faster. This will result in deep discharged old batteries. Therefore, we could consider moving the current/old set to our future octagonal cabins. As depicted in the illustration above, we could run two independent 12 V systems in different locations. Rolls Battery released a new version of our current batteries, the S12 185 ([data sheet](https://www.rollsbattery.com/battery/s12-185/?pdf=8512)). Here is a [summary of the model updates](https://rollsbattery.com/wp-content/uploads/2019/05/Model-Updates.pdf).
