PV mode Basic specifications
Input
(Fixed channels)
(Automatic setting of conversion ratio)
[unit1-ch1] Voltage measurement mode, 1 V f.s., 1,000 V conversion ratio
[unit1-ch2] Current measurement mode, 1 V f.s., 1,000 A conversion ratio
[unit1-ch3] Insolation measurement mode, 20 mV f.s., 140 kW/m2 conversion ratio
[unit1-ch4] Panel temperature measurement mode, K thermocouple 100C f.s., 1C conversion ratio
Expansion channel settings [unit1-ch5] to [unit1-ch11] Select and add as voltage, thermocouple, or clamp (2,000 A, 200 A, 100 A, 20 A, 10 A).
*[unit1-ch12] to [unit1-ch15] and [unit2-ch1] to [unit2-ch15] cannot be used in PV mode.
Equations
(Fixed channels)
(Automatic setting of equation)
[W1] Power (kW) = Voltage (Ch. 1-1) current (Ch. 1-2)
[W2] Power integration (kWh) = Voltage (Ch. 1-1) current (Ch. 1-2) measurement time (h)
[W3] Estimated power (kW) = Insolation strength (Ch. 1-3) / Gs (standard test condition of 1 kW/m2) (1 + temperature loss*1) (1 - coefficient for other losses) photovoltaic cell rated output (kW)
[W4] Estimated integration (kWh) = Insolation strength (Ch. 1-3) / Gs (standard test condition of 1 kW/m2) (1 + temperature loss*1) (1 - coefficient for other losses) photovoltaic cell rated output (kW) measurement time (h) *1 Temperature loss = Photovoltaic cell maximum output temperature coefficient (panel temperature (Ch. 1-4) - 25) / 100
[W5] AC estimated power (kW) = Estimated power (w3) power conditioner conversion efficiency (reference value)
[W6] AC estimated integration (kWh) = Estimated energy (w4) power conditioner conversion efficiency (reference value)
[W7] Estimated power approximation rate (%) = Energy (w2) / estimated energy (w4)
Display PV Wave + Value, PV Wave + Crsr, Gauge + PV Wave, PV Value, Estimate Power, AC Estimate (reference values)
Other specifications Functionality is identical to that of the LR8400-20 when PV mode is OFF.
