1 Install Instructions

*before starting with electrical installation take a look at the thermal management the SBMS needs a heatsink in most cases)

Step 1

Connect the Batt+ power connector to battery positive terminal with a ma 2m of 16mm2 (#6AWG) fle ible copper wire with 200°C

silicone insulation (check page 11 for more details about the recommended cable).

Make sure this is the first connected and the last to be removed.

Step 2

Connect the 10pin monitor and balancing cable. Make sure this is the second one to be connected after Batt+ and never disconnect

while anything else is connected except for Batt+. (see details on page 3 or Parameter Settings on how this has to be connected to

individual cells).

Step 3

Go to Parameter Settings menu and select the type of cell, number of cells and battery capacity then push Store Parameters button to

save data to SBMS. Then remove the 10pin connector and reconnect for the new stored parameters to be accepted.

*you need to be connected to battery to Store Parameters will not work on USB power since ISL94203 is not powered.

Step 4

Go to monitoring menu page 3 and push ok button then a small sub menu will be displayed in the top left corner. Use down key to select

Load OFF and then push OK to enable this.

You should see CFET and DFET flags change state from highlighted to not being highlighted meaning that load+, PV1 and PV2 are

disconnected internally.

Step 5

Connect Load+ using the same type of cable mentioned in step1 to a 125A circuit breaker in OFF position and from there to your load.

Step 6

Connect the PV1 and or PV2 to your PV array to appropriate size circuit breaker in OFF position.

See the page 16 for the type of PV panels recommended based on the number of cells and battery voltage.

Step 7

Switch the Load and PV breakers to ON position and then go again to page 3 of the monitoring menu and select Load ON this time.

The CFET and DFET should be highlighted and the Load should now have power also the PV1 and PV2 should provide charging

current.

Step 8

Check the first page of the Monitoring Menu to see if all works correctly. You are done. Make sure you follow the install procedure in

reverse when you want to remove the SBMS. Never remove the Batt+ or 10pin cell monitoring connector while PV1, PV2 or Load+ is

connected.

2 Thermal Management

The SBMS60 and SBMS100 will need to be mounted on an appropriate size heatsink able to dissipate the ma TDP (Total Dissipated

Power) that is as high as 22W for SBMS100 and 14W for the SBMS60 at full load (charge and discharge at the same time).

The SBMS has two ( 5mm ) mounting holes as you see in the below drawing.

10 SBMS100 / SBMS60

SBMS100 / SBMS60

www.ElectroDacus.com

The SBMS100 without any heatsink or fan can at most dissipate 4W to 5W so below is an e ample with lower power to allow this.

E ample SBMS100 with ma 40A load and 24A on each PV

on Load+ TDP = 40A 40A 0,001Ω = 1,6W

on PV TDP = 24A 24A 0,0024Ω = 1,38W

Total 1,6W + 1,38W + 1,38W = 4,36W

So 40A load and 48A charging is around ma supported by SBMS100 without a heatsink.

The SBMS has an internal 10k thermistor installed on the power board and will measure and

display the temperature of that board. If temperature e ceeds +60°C the charging and

discharging will be turned off and only turn on the charging and discharging when

temperature drops below +50°C.

If size and weight is of great concern in your installation a low speed fan can be used to cool the back of the SBMS.

If SBMS is not used with full configuration then a smaller heatsink can be used or even no heatsink at all.

You can use the simple formula below to calculate the TDP.

TDP[W] = I[A] I[A] R[Ω]

For e ample you need to know the R for Load+ and PV1/PV2. Load+ resistance path on SBMS100 is 1mΩ and SBMS60 is 1,5mΩ

where PV input on SBMS100 is 2,4mΩ and on SBMS60 is 3mΩ.

For ma configuration on SBMS100 you have:

on Load+ TDP = 100A 100A 0,001Ω = 10W

on PV TDP = 50A 50A 0,0024Ω = 6W

So total 10W + 6W + 6W = 22W on full load SBMS100
