Specifications
mono panels, 25yrs warrantylong lifespan battery
inverter with AC input for back-up
low cost, high efficiency
off grid solar system : solar panel -- controller -- battery -- off grid inverter-- AC loads
Solar panel : Monocrystalline solar panels, 10years output 90% & 25years output 25% of its nominal power rating
Controller : MPPT or PWM charge controller ( Optional )
Battery : Fully sufficient capacity battery, AGM lead acid battery (5-7yrs lifespan) ; GEL battery ( 7-10yrs lifespan)
Off grid inverter : Pure sine wave output, isolated transformer inside, better stability than transformerless type.
with AC input for backup. that menas, inverter auto transfer to state grid / generator to take electricity for AC loads when low battery. this function is to ensure the normal operation of AC loads if bad weather last so long.
