Technical Specifications

What is the Deye SUN-5K-SG04LP1-AU hybrid inverter?
The Deye SUN-5K-SG04LP1-AU is a 5kW single-phase hybrid solar inverter that stores solar energy in a battery for use at night or during outages. It has two MPPT trackers, accepts up to 7,500W of solar input, supports 48V lead-acid and lithium-ion batteries with up to 120A of charge and discharge current, and works on-grid or off-grid. It suits NZ homes that want solar by day, stored power by night and less reliance on the grid.

What batteries are compatible with the Deye SUN-5K-SG04LP1-AU?
The Deye SUN-5K-SG04LP1-AU works with lead-acid and lithium-ion batteries in the 40–60V range. It supports up to 120A of charge and discharge current, uses self-adaptive BMS communication with lithium-ion batteries, and allows multiple batteries side by side as your storage needs grow.

How much solar can I connect to the Deye 5kW single-phase hybrid inverter?
The Deye 5kW single-phase hybrid inverter accepts up to 7,500W of DC solar input, a 1.5× ratio to its 5,000W AC output. Panels connect across two MPPT trackers with one string each, within a 150–425V MPPT range and a 125V start-up voltage. Each tracker handles up to 13A of operating current.

Why does the Deye SUN-5K-SG04LP1-AU have two MPPT trackers?
Two independent MPPT trackers let the Deye SUN-5K-SG04LP1-AU optimise panels on two roof faces or under shifting shade separately, with each string running at its own peak. MPPT efficiency reaches 99.9%, so very little potential solar yield is lost.

Can the Deye 5kW hybrid inverter run off-grid?
Yes, the Deye 5kW hybrid inverter supports both on-grid and off-grid operation. In off-grid mode it delivers twice its rated power for 10 seconds to start heavy loads, and it can store energy from a diesel generator for backup when solar isn’t available.

Can I add the Deye SUN-5K-SG04LP1-AU to my existing solar system?
Yes, the Deye SUN-5K-SG04LP1-AU supports AC coupling, so you can add battery storage to an existing solar system without removing your current inverter.

Can I schedule when the battery charges and discharges?
Yes, the Deye SUN-5K-SG04LP1-AU has six programmable time periods for charging and discharging. You can shift battery use around peak tariffs to lower your electricity bill.

How many Deye SUN-5K-SG04LP1-AU inverters can be connected in parallel?
Up to 16 Deye SUN-5K-SG04LP1-AU inverters can be connected in parallel for on-grid or off-grid systems, so the system can grow as your energy needs expand.

What is the AC output and passthrough rating of the Deye 5kW hybrid inverter?
The Deye 5kW hybrid inverter delivers 5,000W of rated AC output at 21.7A, with a 35A maximum continuous AC passthrough. Grid power can flow through to your loads even when solar and battery aren’t contributing.

How efficient is the Deye SUN-5K-SG04LP1-AU?
The Deye SUN-5K-SG04LP1-AU has a maximum efficiency of 97.6%, a Euro efficiency of 96.5% and an MPPT efficiency of 99.9%, keeping conversion losses low every day.

Can the Deye 5kW single-phase hybrid inverter be installed outdoors?
Yes, the Deye 5kW single-phase hybrid inverter has IP65 protection against dust and rain, so it can be installed outdoors. A colour touch LCD on the unit makes setup and monitoring straightforward.

How big and heavy is the Deye SUN-5K-SG04LP1-AU?
The Deye SUN-5K-SG04LP1-AU weighs 17kg and measures 330 × 433 × 229mm, excluding connectors and brackets.

Should I choose the Deye 5kW or 3.6kW single-phase hybrid inverter?
The Deye SUN-5K-SG04LP1-AU offers 5,000W of AC output, up to 7,500W of solar input and 120A of battery current. The Deye SUN-3.6K-SG04LP1-AU offers 3,600W of output, 5,400W of solar input and 90A of battery current. Both are 48V hybrid inverters with two MPPT trackers, a 150–425V MPPT range, a 35A AC passthrough, IP65 protection, up to 16 units in parallel and the same 17kg, 330 × 433 × 229mm cabinet. The 5kW model suits larger arrays and higher household consumption.

What is the difference between the Deye 5kW hybrid inverter and the 5kW grid-tied string inverter?
The Deye SUN-5K-SG04LP1-AU hybrid inverter manages battery storage, off-grid operation, generator charging and backup power. The Deye SUN-5K-G05P1-AU-AM2 grid-tied string inverter only converts solar power for your home and the grid, with no battery input. Choose the hybrid for storage or backup, or the string inverter for a simple grid-connected system.
