How to Use This Calculator
Enter your panel count and wattage
Hoymiles microinverters are grouped in units that handle 4 or 6 panels each. Enter the total number of panels in your system (4–32) and each panel's rated wattage (380–700W). The calculator selects the best-fit Hoymiles model and tells you how many units you need.
Understand the model selector matrix
Hoymiles HMS-1600T and HMS-2000T each handle 4 panels with 2 AC outputs — the right choice for small rooftop systems of 2–4 panels per unit. The HMS-2250DT and HMS-MIN handle 6 panels with 3 AC outputs, providing per-panel MPPT optimization ideal for shading scenarios and bifacial dual-input panels. The HMT-2250 adds a 4th AC outlet for 3-phase commercial connections.
Compare against Enphase IQ8
Hoymiles microinverters cost $0.20–0.30/W versus Enphase IQ8's $0.35–0.45/W — a 30–40% price difference that often equals thousands of dollars on a full residential system. The calculator shows your exact savings. The trade-off: Enphase has a larger installer network in the US and full IRA domestic content eligibility. Hoymiles is dominant in Europe, Australia, and cost-conscious US installs.
The Formula
The HMS-1600T handles panels up to 400W each (4 × 400W = 1600W max). The HMS-2000T handles panels up to 500W each (4 × 500W = 2000W). The HMS-2250DT and HMS-MIN handle 6 panels at up to 375W each — or dual-input bifacial panels where each physical panel uses 2 inputs. The HMT-2250 provides a 3-phase output for grid connections requiring 3-phase injection.
Example
Carlos — 12 panels @ 450W, replacing Enphase quote
Carlos received an Enphase IQ8 quote for his 12-panel, 5.4 kW system. He wants to compare Hoymiles as a budget alternative while maintaining per-panel monitoring and shade tolerance.
Results
Carlos saves approximately $600 on inverter hardware alone. He gets identical per-panel MPPT optimization and real-time monitoring via Hoymiles S-Miles Cloud. The trade-off: Enphase has more certified installers in his area, and he cannot claim the IRA domestic content bonus with Hoymiles equipment.
