# Solar panels and MPPT charge controller
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 750 W to the [SolarEpic 4215BN MPPT Solar Charge Controller](https://solarepic.com/products/solarepic-mppt-40a-solar-charge-controller-150v-pv-input-tracer-4215bn?variant=12497866457137) ([manual](https://www.epsolarpv.com/upload/file/1903/Tracer-BN-SMS-EL-V1.2.pdf)). The charge controller is rated for 40 A.
The additional, older 250 W panel is connected to a small PWM charge controller. Note that PWM charge controllers are less efficient than MPPT controllers.
The Main House Electricity System is connected to an Arduino-based [[Electrical Control Unit]]. Please refer to the aforementioned page for the GitHub repository.
# Generators
The large, yellow generator behind the house is used to charge the batteries through the inverter whenever the battery voltage is low. The champion 3650 generator ([manual](https://y79961nbs4u2hvbnwronx9zx-wpengine.netdna-ssl.com/wp-content/uploads/2017/08/100216-om-english.pdf )) can supply up to 3650 watts. However, it will be much happier around 1000 watts. You can set the charging amps on the inverter. We recommend no more than 6 A (around 700 watts) for charging the batteries.
