what difference 48V and 192V 15KW Electricity solar equipment?

15KW Electricity solar equipment with one inverter design

15kw Electricity solar equipment with three inverter design

TANFON Configuration

48 pieces solar panels

1piece 15KW / 192V IGBT inverter

32 pieces Rechargeable batteries

Other Configuration

48 pieces solar panels

3piece 5KW/48V  inverter

40 pieces Rechargeable batteries

TANFON Electricity solar equipment connect:

DC voltage 192V.

Solar panel connection: 8pcs pieces in series, 6pcs strings in parallel

Battery connection: 16pcs series, 2 string in parallel

TANFON Electricity solar equipment connect:

DC voltage 48V

Solar panel connection mode, 2 pieces in series, 24 strings in parallel

Battery connection:4pcs in series, 10 strings  in parallel

Solar Inverter material:

IGBT, stronger, can carry all inductive loads

have transformer,Low frequency inverter

is more strong take all inductive load.

Solar Inverter material:

MOS tube, conventional material

without transformer ,high frequency

analysis:

The DC voltage is large, so the current is small and more stable

2pcs batteries in parallel, high system consistency

More stable with large loads

analysis:

The DC voltage is small, so the current is large and unstable

10pcs batteries in parallel, the factory requires no more than 4 batteries in parallel

Because three 5KW inverters are connected in parallel, it is not safe for large loads exceeding 5KW.

15KW / 192V Electricity solar equipment application:

suitable for general household, commercial, farm, industrial

15KW / 192V Electricity solar equipment application:

Suitable for specific places, the battery pack must be used in 48V places
