The RPS will provide renewable power continuously providing the available energy
IN is equal or greater than the energy OUT.
It is suggested that the first few weeks of operation of each season be recorded
from sunrise (typically the lowest daily voltage) to sunset (typically the highest
daily voltage) to determine sustainable system levels.

The system is sustainable (able to provide purely ‘renewable’ power) when the
Battery Voltage at sunrise is consistently above the battery cutoff voltage
(approximately 10-15% charge level).
If the System Voltage is below the sustainable voltage level (where the system
turns itself off) consider reducing the equipment load on the RPS, add a Battery
Pack, or another RPS.
If the System Voltage cannot support the energy needs during sunlight hours,
consider reducing the equipment loads, or add another RPS.
