hybrid inverter

[ddaky]

hello...im looking to start my solar adventure and found this solar inverter...now the more im looking and reading the more is complicated for me
if i understand hybrid can use solar and grid at the same time?
for now i have only 1kw solar panels so when the sun is shining and my house is pulling lets say 1500w inverter will provide 1000w from solar and 500w from grid?
this is inverter i found...maybe someone is familiar with this

Your first link shows a grid tie/off grid inverter. So yes it can parallel with grid and share loads depending on settings and availability of PV/battery. Be aware that it may need utility company approval and pass inspection. Hybrid is a bit of a indeterminate term. It can applied to both grid tie and strictly off grid AIO's. It simply means that the AIO makes use of the grid plus PV/batt. Off grid AIOs sometimes are called grid assist as they do not parallel with grid but act like a UPS (Uninterruptible Power Supply) to maintain power.

thanks for reply....after a litle more reading i found out that i cant send my excess power back to the grid so i dont now what are my options now...is there any inverter that can use bouth grid and solar but without option to send power to the grid...i found this one where is stated

Solar Inverter 500Vdc 5000W 80A MPPT Parallel Inverter 48V 230VAC Pure

Solar Inverter 500Vdc 5000W 80A MPPT Parallel Inverter 48V 230VAC Pure Sine Wave Hybrid Inverter With Battery Charger ###This inverter also has a On-Grid function (can sell excess power to the grid) Max.can be 9 pcs in parallel with optionalkit Efficiently work with or without battery MPPT...

There are grid tie AIO hybrids that claim "Zero export" to grid. This is accomplished by using CT's on incoming grid wires to measure amount of current flow/direction and reduce the AIO's output as home loads change to avoid back feeding to grid. But once again your utliity company may require an interconnect agreement and inspection to ensure that your components are certified by appropriate National certifications labs.

and off grid inverters use solar while it have plenty of w but as soon as it cross over max of solar it automatically transfers to grid?

Off grid AIO with grid supplied to the "AC in" connection will run loads on the "AC out" connections based on availability of PV/battery plus the mode of operation selected in the settings of inverter. If there is not enough of one of these supplies than the ATS (Automatic transfer switch) portion of the unit will transfer to another source. There are a few off grid inverters that can run without batteries strictly off PV with grid adding a bit but not being in parallel with grid. They can be a bit problematic in operation.

what would you recommend to me?i dont have battery's and will not have them in near future i want to use my panels

Sorry, I have no experience in using one of the types of AIO's that claim to work without battery. There are people on the Forum that do have such experience. You may need to create a new Thread asking about, "Can someone recommend a Off grid AIO's that operates without battery?"
