Inverters · Hybrid IP66 · three phase
8 kW inverter, 380/400 VAC · 48 V output, 1 MPPT, PV range 200 – 800 V, protection rating IP66. Imported through official channels with full CO · CQ paperwork, 5-year warranty.
The GP3-8KS48P3 is a three-phase hybrid inverter rated 8 kW, output 380/400 VAC · 48 V. Hybrid means that besides converting panel power for immediate use, it can also charge and discharge a storage battery — daytime surplus is kept for the evening, and priority loads keep running through a grid outage.
The maximum PV input of 16.000 W is the total panel capacity you may connect — about 25 panels of 630 W, or 2 times the inverter's own rating. Oversizing like this is normal and advisable: panels only reach their nameplate figure in the brightest sun, and fall well short in early morning, late afternoon and cloudy weather. An array larger than the inverter keeps it near design output for more hours of the day.
It has a single MPPT, so the whole array runs on one tracking circuit. That suits a roof with a single orientation. On a roof split across several faces, one MPPT means the shaded side drags the whole array down.
The PV voltage range 200 – 800 V is the window in which the inverter can track power. The number of panels in series must be worked out so the string voltage stays inside it both on a cold morning — when open-circuit voltage is highest — and at hot midday, when it sags. Leave this to an engineer: exceeding the upper limit can damage the unit.
Protection rating IP66, weight 44 kg. That rating is fully dust-tight and withstands powerful water jets, so it can be wall-mounted outdoors. Even with a weatherproof case, hang it in shade or add a small canopy: in direct midday sun the unit heats up and derates itself to protect its components — losing output exactly when the sun is strongest.

FAQ
Maximum PV input is 16.000 W. Divided by a 630 W Mono panel that is roughly 25 panels — 2,0 times the unit's 8 kW rating. That headroom is intentional: panels rarely reach their nameplate output, so oversizing brings the inverter up to full power earlier in the morning and holds it later into the afternoon. The real count also depends on roof orientation and the 200 – 800 V voltage window, so the strings need working out before you commit.
The unit is rated 8 kW with a 380/400 VAC · 48 V output. That size suits a large townhouse, a shop or a small workshop. The number to work from is what the roof can produce, not the inverter rating: size the inverter against the total panel wattage you plan to install, then check it against the 16.000 W ceiling above.
Yes. IP66 means the unit is fully dust-tight and resistant to powerful water jets from any direction. Even so, avoid all-day direct sun: at high temperatures the inverter derates itself to protect its components, costing you output in exactly the brightest hours. A small canopy, or a north-facing wall, is enough.
This unit has a single MPPT tracker, so the whole array must share one orientation and one tilt. Each MPPT tracker finds the maximum power point for the group of panels wired to it. Two groups facing different directions, or at different tilts, sharing one tracker force it to pick a single compromise point, and neither group runs at its best. The same applies where a tree or a chimney shades part of the roof.
The GP3-8KS48P3 belongs to the Hybrid IP66 · ba pha group. A grid-tie unit: what it makes is used on site and the surplus goes to the grid. If the grid goes down the inverter disconnects itself as the safety rules require, so without a battery there is no power.
