// The documented register for setting the charge/discharge power for forced mode is 13052.
|
||
|
|
//
|
||
|
|
// HOWEVER, this register can't be set (neither via Modbus nor via WiNet-S register setting). On the other hand, the
|
||
|
|
// Energy Management Parameters tab lets you set this value, but inspecting the web requests reveals it uses register
|
||
|
|
// 33148!
|
||
|
|
//
|
||
|
|
// This example, therefore, uses register 33148. However, unlike the documented 13052, the value here is set in
|
||
|
|
// multiples of 10W (e.g. `200` is 2000 Watts).
