String by climatic region
T_min per ДСТУ-Н Б В.1.1-27:2010, табл. 1; open-circuit voltage at T_min: K_U = 1 + α·(T_min − 25)/100 = 1.17 (α -0.25 %/K, T_min -42 °C; Annex B).
| Region | T_min | Panel U_oc at T_min, V | Min per string | Max per string | String U_oc at max, V (≤ 1,100) |
|---|---|---|---|---|---|
| Region I | -40 °C | 61.50 | 4 | 17 | 1,045.4 |
| Region II | -42 °C | 61.76 | 4 | 17 | 1,049.9 |
| Region IIIA | -38 °C | 61.23 | 4 | 17 | 1,040.9 |
| Region IIIB | -32 °C | 60.44 | 4 | 18 | 1,087.9 |
| Region IV | -20 °C | 58.85 | 4 | 18 | 1,059.3 |
| Region V | -27 °C | 59.78 | 4 | 18 | 1,076.0 |
The minimum per string keeps the string voltage in heat (panel V_mp 37.6 V) above the MPPT window (120 V).
Input currents
| Panel I_sc / MPPT input I_sc, A | 14.07 / 19.5 |
|---|---|
| Panel I_mp / MPPT input I_mp, A | 13.36 / 13.0 |
| Parallel strings per MPPT | 1 |
| MPPT inputs | 2 |
- Power clippingThe panel's working current (13.36 A) is above the input's working current (13.0 A): on clear days the inverter clips part of the power.
Example plants
The Solispec engine laid out the strings for plants of several sizes with this inverter at the lowest T_min; only those that pass the checks with every panel placed are shown.
| Plant | Panels | kW DC | Inverters | Strings | DC/AC |
|---|---|---|---|---|---|
| ≈ 5 kW | 9 | 5.31 | 1 | 9 pan. × 1 — inv. 1, MPPT 1 | 0.53 |
| ≈ 10 kW | 17 | 10.03 | 1 | 17 pan. × 1 — inv. 1, MPPT 1 | 1.00 |
| ≈ 15 kW | 26 | 15.34 | 2 | 13 pan. × 1 — inv. 1, MPPT 1; 13 pan. × 1 — inv. 2, MPPT 1 | 0.77 |
- current 13.4 A > 13 A — the inverter will clip (clipping)
- DC/AC 0.53 — inverter oversized
- U_OC MAX 1 050 В > 1000 В — звірте максимальну напругу системи панелей і апаратів (паспорт, 712.512.1.1)
