Description

System voltage is allowed up to 1,100 V with operation up to 1,000 V, so strings can be long at a 620 V rated input. Each MPPT takes up to 40 A and each input 20 A, enough for high-current modules. The CI 30 has three trackers and 6 inputs, the CI 50 four trackers and 8 inputs, with MPP ranges at rated output of 420–850 V and 500–850 V. Type 2 surge protection sits on both AC and DC, an RCMU type B watches leakage, and AFCI arc detection trips the DC circuit on arcing. The inverter runs at ambient temperatures from −25 to +60 °C and up to 4,000 m, so no separate room is needed. The 3N~ 230/400 V output gives 33.4 kVA on the CI 30 and 55.6 kVA on the CI 50 at 43.5 A and 72.5 A rated current.

How to choose

Pick the model by the array, up to 45 kWp on the CI 30 and 75 kWp on the CI 50, and size the breaker at B63/C63 or B125/C125. The earlier PIKO CI 30 / 50 / 60 series reaches 66 kVA and 12 DC inputs when one unit needs more headroom. For backup or a battery take the PLENTICORE G3 hybrid up to 20 kW. Plants at 100 kW are covered by the PIKO CI 100.
