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 (≤ 550) |
|---|---|---|---|---|---|
| Region I | -40 °C | 50.87 | 3 | 10 | 508.7 |
| Region II | -42 °C | 51.09 | 3 | 10 | 510.9 |
| Region IIIA | -38 °C | 50.65 | 3 | 10 | 506.5 |
| Region IIIB | -32 °C | 50.00 | 3 | 11 | 550.0 |
| Region IV | -20 °C | 48.68 | 3 | 11 | 535.5 |
| Region V | -27 °C | 49.45 | 3 | 11 | 543.9 |
The minimum per string keeps the string voltage in heat (panel V_mp 30.9 V) above the MPPT window (70 V).
Input currents
| Panel I_sc / MPPT input I_sc, A | 13.93 / 27.0 |
|---|---|
| Panel I_mp / MPPT input I_mp, A | 13.38 / 18.0 |
| Parallel strings per MPPT | 1 |
| MPPT inputs | 2 |
No cautions about the currents.
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 | 11 | 5.34 | 1 | 6 pan. × 1 — inv. 1, MPPT 1; 5 pan. × 1 — inv. 1, MPPT 2 | 1.07 |
| ≈ 10 kW | 21 | 10.19 | 2 | 7 pan. × 1 — inv. 1, MPPT 1; 7 pan. × 1 — inv. 1, MPPT 2; 7 pan. × 1 — inv. 2, MPPT 1 | 1.02 |
| ≈ 15 kW | 31 | 15.04 | 4 | 4 pan. × 1 — inv. 1, MPPT 1; 4 pan. × 1 — inv. 1, MPPT 2; 4 pan. × 1 — inv. 2, MPPT 1; 4 pan. × 1 — inv. 2, MPPT 2; 4 pan. × 1 — inv. 3, MPPT 1; 4 pan. × 1 — inv. 3, MPPT 2; 4 pan. × 1 — inv. 4, MPPT 1; 3 pan. × 1 — inv. 4, MPPT 2 | 0.75 |
- DC/AC 1.36 — will clip peaks
- DC/AC 0.68 — inverter oversized
