// DC OVERSIZING

More Panels
= More Power Output

Solis supports DC input up to 1.6× the inverter's rated power — capture every watt at sunrise, sunset, and on cloudy days. Never leave production on the table.

Standard · 1:1

Typical Inverters

10 kW

A 10kW inverter + 10kW of panels matched exactly — when sunlight is weak, the system produces far less than its potential

10 panels · average real output ~75%
Solis · up to 1.6:1

Solis Hybrid Inverter

16 kW

A 10kW inverter + up to 16kW of panels — capture energy from morning, evening, and overcast skies. Boosts annual yield by +15-25%.

+6 extra panels · production +15-25% per year
// Smart Mode

Smarter than just a converter

Solis S6 goes beyond a standard inverter — featuring Generator port · Smart Load · Peak Shaving · and scheduled appliance control

Generator Port

Connect a diesel generator through a dedicated input — auto-starts when the grid fails and the battery is depleted · uninterrupted power

Auto Start Bypass

Smart Load

Control appliances on/off (water heaters, pumps, AC) based on sunlight or battery SOC — use free PV power first

Time-based SOC-based

Peak Shaving

Cut peak-hour costs — draw from the battery instead of the grid when rates are highest · ideal for factories on TOU tariffs

TOU Demand cut

Frequently Asked Questions

What's the difference between Hybrid and On-Grid — which should I choose?
On-Grid has no battery — it generates power for daytime use and sells excess to the grid · won't work during blackouts · lower starting price (5kW ≈ 15,000฿). Hybrid includes a battery port — store generated power for nighttime use and stay running during outages · higher price (6kW ≈ 26,000฿), but worthwhile in an era of rising electricity costs. We recommend Hybrid if you have an extra +20,000-30,000฿ budget and need backup power.
What does 1.6× DC oversizing mean?
A Solis 10kW inverter accepts DC input up to 16kW (1.6×) — meaning you can install up to 16kW of total panel capacity. Why does this matter? Solar panels rarely produce at full spec — in the morning, evening, or under clouds, output is only 30-60%. Oversizing the array captures more power during low-light periods without damaging the inverter (clipping is handled automatically). Annual yield increases by 15-25%.
What's the difference between S6-EH3P-NV-YD-L (LV) and S6-EH3P-H (HV)?
LV (Low Voltage) uses a 48V LFP battery (e.g. QES Battery 16kWh) · easier to install · more affordable · ideal for small-to-medium systems 10-15kW. HV (High Voltage) uses a 200-865VDC stack · 1-2% higher efficiency than LV · best for large systems 20-50kW. Choose HV if you have the budget and need maximum efficiency · consult QES to match the right inverter + battery combination.
How long is the warranty?
Solis includes a full 10-year warranty by default on every model — no extra registration or extended warranty purchase required · covers any manufacturing defects on the inverter · QES Energy handles the full warranty claim process for you.
Which battery brands are compatible?
Solis works with most Lithium batteries that communicate via standard CAN / RS485 protocols — LV models use 48V LFP · HV models use 200-865V stacks · QES recommends pairing with the QES Battery 16kWh IP65 (LV) — a perfect match with one-stop pricing and service. For other brands or HV options, contact QES for the compatibility list.
Does it really have AFCI for fire protection?
Every Solis S6 model has AFCI built-in or AFCI optional (selectable) · detects DC Arc Faults from degraded panels/wiring and cuts power within 0.5 seconds · meets UL 1699B / IEC 63027 standards · significantly reduces fire risk in solar systems.
