Description
The power range consists of the 3 and 3.6 kW versions, the 5 and 6.6 kW versions and the top 8.8 kW one. The two MPPT trackers accept PV modules from two roof slopes or two groups with different orientation, and the Wi-Fi module is already inside the enclosure, so a separate logger is not needed. The battery current reaches 190 A, and it determines the battery cable cross-section and the fuse rating between the battery and the inverter. The switchover to battery power takes 4 ms, so computers and boilers do not reboot. The maximum efficiency is 97.6 %. The IP65 enclosure is protected from dust and water jets, and the inverter can be installed in an unheated room or under a canopy. At a weight of 8.6 kg it can be hung on a wall by one person without lifting equipment.
How to choose
The power is chosen by the peak load of the house, not by the average consumption, because starting a pump or compressor causes a short current surge. If one 8.8 kW inverter is not enough, up to 16 units and up to 32 batteries are connected in parallel, expanding the system without replacing equipment already installed. Where the grid is stable and a battery is not needed, a grid-tied SUN-G P1 rated 1–10.5 kW with zero export is more suitable, and for three-phase sites there is the SUN-G06P3 rated 3–25 kW.

FAQ
How many SUN-OG03LP1 inverters can be connected in parallel?
Up to 16 inverters, and up to 32 batteries can be connected to such a system.
What is the maximum battery charging current of the off-grid inverter?
The battery current is up to 190 A, and cables and a DC protection device are selected for it.
Will computers notice the transfer to battery power?
The switchover time is 4 ms, so most office equipment and gas boilers keep running without restarting.
How much does the off-grid inverter weigh and where can it be installed?
The inverter weighs 8.6 kg, and the IP65 enclosure allows installation in an unheated room or under a canopy.
How many MPPT trackers does the SUN-OG03LP1 off-grid inverter have?
Two MPPT trackers, so the PV modules can be split into two groups with different orientation. The maximum efficiency is 97.6 %.
