Goodwe 5048ES with BYD B-BOX (2.5-10) Installation Guide

Attention:

Goodwe 5048D-ES in this manual is the new one with serial number starting with 9 ie 95048ESU16XXXXX.

For the Goodwe 5048D-ES with starting SN 3, please refer to other document.

Index

1. Physical wiring

2. APP configuration

3. System function review

4. WiFi set up

5. Could Account Registration

6. Check List

Part 1: Inverter and battery physical connection

1.1 DC POWER connection (Battery and PV connection)

Referring to Goodwe ES manual 4.1 & 4.2 as well as BYD battery manual for physical connection

1.2 AC POWER connection

Goodwe 5048D-ES inverter has the grid connected and back up connection at the bottom of

inverter.

Customer could connect essential loads to the back up supply part so that when the grid is off,

the inverter still support back up load within 8ms.

During the grid connected condition, the inverter still recognize back up and grid tied load as

entire load, support these loads from PV, battery and grid. Even when there is no available PV

and battery, the inverter still use the grid power to support both loads.

Circuit diagram:

Attention point:

a. According to Australian Standard, when customer is using the back up load, the neutral cable

between the inverter back up part and neutral cable from grid connected part must be

jumped together. Installer can jump cables at the bottom of inverter or on the neutral bar.

b. 5048D-ES back up max power output is 4.6kW, however there is further load definition must

be compliant by using back up mode (or off grid scenario). When using the inverter as off

grid system, once the back up load is oversize, the inverter’s fault light will blinking and

inverter will shut down for self-protection.

c. Do NOT connect the grid to inverter’s back up part under any scenario. The inverter could be

damaged if there is power flows into the inverter from back up part.

d. To improve the system reliability, Goodwe recommends installer to install a changeover

switch between back up load and grid tied load. Then for rare case, if the inverter is faulty,

customer could manual switch all essential house loads back to the grid side.

1.3 Data cable connection

5048D-ES needs to communicate with Ezmeter (in the package box) and the BYD battery for

normal operation. These communications are both through premade factory CAT5 cables.

To the meter

5048D-ES inverter offered together with an ezmeter which is for monitoring the load.

Attention point:

a. Part 1 on top of meter connects to power cable; part 4 on top of meter connects to neutral

cable for powering up the meter.

b. CT position is between the main switch and the customer power meter.

c. CT clamp has its direction:

There is clear label on CT to indicate the right orientation. On the label, HOUSE indicates house

side, GRID indicates GRID side.

To wrongly put the meter, the monitoring will have abnormal data. If the house load is unusual

high and equal to PV plus Grid, then this indicates the CT clamp connected reversely wrongly.

d. Check the CT tiny cable connected to the meter, the part 5 is white cable, part 6 is black

cable.

e. The premade factory cable to ezmeter on inverter can be unplugged and plug the new one if

the distance is not long enough.

To the battery

Cut the crystal terminal off, remake the data cable to only have Blue on pin 4, Blue/White on pin

5.

Then refer to BYD manual for giving the battery address, set up physical cable between batteries.

Turn the system ON:

Procedure of turning system ON:

Turn the PV firstly, following by battery, then ac grid after physical wiring completed.

The inverter LED indicator lights will start to be ON. The indication of each LED is below:

The same label is on left side of inverter.

Part 2: APP configuration

Goodwe offers the free Ezmanage APP for set up the system, please download the APP from

Apple store and Android shop.

2.1 Fristly, connect mobile&tablet to ‘solar-wifi’on the device, password is

12345678

2.2 Then open the ‘ezmanage’

2.3 Select the ES series

2.4 Push ‘Set’button

2.5 To Basic setting page, type in the password ‘Goodwe2010’

2.6 Select the country: In Australia, we offer Australia, AU Ergon, AU Energex

When select the AU ergon or AU Energex, it will follow these local special

standards.

2.7 Push ‘Next’to select the working mode.

For standard system, please select the general model which is maximum

self-consumption.

For off grid system, please select the off grid model

If customer requires charge from or discharge to grid in specific period, then

select Economical Mode for defining the charge/discharge period.

Power limit means the charge/discharge rate. Ie, if the charge power limit is 50%, it means the

inverter charge from grid at 2.3kW (50% of 4.6kW).

2.8 Push ‘Next’to select the battery type

So far, Goodwe offered B-BOX2.5 –10, four options, depends

on the real battery bank.

2.9 Once selected the battery type, push the start button.

Ezmanage will pump out the window to enquire whether restart the inverter for saving these

settings. Push ‘YES’then inverter restarts itself for saving settings.

2.10 For customer who is using back up wiring and zero export function:

Still push the ‘Set’button, then push the ‘advanced setting’.

The password ‘Goodwe2010’

a. To open the back up function.

Simply turn the back up supply button from left to right (green

colour). Once selected, push the ‘Return Arrow’back to main page.

Ezmanage will pump out the window enquire for restarting the

system. Push ‘YES’then inverter will restart itself automatically.

The back up indicator light on inverter will be solid to indicate the

back up function is ON.

b. To open the export power limit.

Simply turn the export power limit function on. It is not only 0kW export. Customer can define

the max power export limit by type in the number in W in Power Limit table.

Part 3: System Review

To ensure Goodwe 5048D-ES is communicating with BYD Box and Goodwe ezmeter, there are two

parts need to be checked.

a. Meter Status

Since finish part 1 & part 2, still connect the mobile to the solar wifi. Push the ‘Param’on

home page, push the ‘Grid’, the meter status should be ‘OK’.

b. Battery Communication

Push the ‘Param’on home page, push the battery, the battery BMS status should be ‘Battery

Communication OK’. (Need to push the Battery Com to see the full indication)

Once confirmed these two communications are OK, then the system is fully commissioning.

Part 4: WiFi set up

Goodwe 5048D-ES inverter has two ways for monitoring.

a. Direct monitoring

Customer could use mobile to connect the solar-wifi, and open the ezmanage for

instantaneous data monitoring on ezmanage home page.

b. Cloud monitoring

Customer can connect the inverter to local wifi, then register on Goodwe cloud for remote

monitoring.
