However, some homeowners with solar panels in Australia and battery storage systems have encountered a puzzling phenomenon – their systems pull electricity from the grid even when the batteries are charged. This seemingly counterintuitive situation can be explained by several factors in Australia''s unique energy landscape. Understanding the system. Not a simple on/off …
I encountered something similar and I think it has to do with the batteries outputs feeding into their own charging circuit. I made a separate relay that feeds into the battery inputs straight from the reactor, and my batteries didn''t drain like they used to. The original idea was to have a button to block charging if the load was too high for the reactor but I ended up just always leaving it ...

An example of this would be a system with a DC battery, AC power and perhaps a solar panel with a different DC voltage than the battery. Power remains the same across the different voltages. For example, if you run an AC load of 2400W via an inverter from a 12V battery, it will also take 2400W from the battery (ignoring the inverter ...

Obviously the power generated by the battery must be equal to the power given to the motor (the controller has very high efficiency). Indicating the duty cycle as DC: Power generated by the battery: Vbb x Iaverage = Vbb x Ipeak x DC. Power received by the motor: Imot x Vmot = Imot x Vbb x DC. Therefore: Vbb x Ipeak x DC = Imot x Vbb x DC. Ipeak ...
For instance, a 40V MAX lithium 4.0Ah battery will provide you with 120 watt-hours of energy. A 20V battery is sufficient for most trimming requirements of a small to medium-sized yard (approximately 20 to 30 minutes of actual cutting). An 80V battery will provide about 45 minutes of run time, which is good for larger yards.
