Common Questions
Click a question below to reveal the answer.
How many string inputs does the Solis S5-GR3P10K have?
The S5-GR3P10K has 2 MPPT trackers with 1 string input each (2 strings total), unlike the larger 15 kW and 20 kW GR3P models which have 2 strings per MPPT (4 total).
Is the Solis S5-GR3P10K fan-cooled?
No. The 10 kW model uses natural convection cooling (no fan), resulting in near-silent operation at less than 30 dB(A). This makes it particularly suitable for residential installations where noise is a concern.
Does the Solis S5-GR3P10K include monitoring equipment?
No. Data logger, CT, meter, and export power manager are sold separately. For single-inverter export control, use the SOL-METER-3PH-CT3 with a data logging stick. For multi-inverter systems, use the EPM3-5G-PRO or EPM3-5G-PLUS.
Can I extend the warranty?
Yes. The standard 5-year warranty (10 years in selected EU countries) can be extended to 10 or 20 years with the appropriate warranty extension parts.
