Description
Five series are gathered under one name: the SG04LP1 rated 3–6 kW, the SG05LP1 rated 3.6–10 kW, the SG06LP1 rated 3–12 kW, the SG02LP1 rated 7.6–12 kW and the most powerful SG01LP1 rated 12–18 kW. The 40–60 V battery input accepts lead-acid or lithium-ion batteries, and the charge and discharge current is 140–380 A depending on the model. The inverter can be connected on the AC side to an existing grid-tied solar plant, so the old inverter keeps working and its surplus goes into the battery. A diesel generator recharges the battery during long outages. The schedule sets 6 time periods with different modes, for example charging at night at a cheaper tariff. The IP65 enclosure is protected from dust and water jets.
How to choose
The model is chosen by the peak power of the loads and by the current the battery can withstand. For an apartment or a small house the SG04LP1 or SG05LP1 is enough, and for a cottage with a heat pump the SG02LP1 or SG01LP1 rated 12–18 kW is taken. If one unit is not enough, up to 16 inverters are combined in parallel, and this works in both grid-tied and off-grid mode. For a three-phase supply with a 48 V battery there is the SUN-SG LP3, and a house without a grid can use the off-grid SUN-OG03LP1 rated 3–8.8 kW and weighing 8.6 kg.

FAQ
Can a hybrid inverter be connected to an already installed grid-tied solar plant?
Yes, through AC coupling. The existing grid-tied inverter keeps working, and the SUN-SG LP1 charges the 48 V battery with the surplus of its generation.
How many single-phase hybrid inverters can be connected in parallel?
Up to 16 units, and parallel operation works in both grid-tied and off-grid mode.
Can the hybrid inverter battery be charged from a diesel generator?
Yes, the inverter charges a 40–60 V battery from a diesel generator, which helps during long outages.
What is the battery charging current of the SUN-SG LP1 series?
Depending on the model 140–380 A, so the larger units need a battery that can withstand such a discharge current.
How many time periods can be set in the inverter schedule?
6 periods, each with its own battery charging or discharging mode.
