Solaredge Control of inverter power output - gjniewenhuijse - 27.03.2024
Is there a way to control the Solaredge inverter power output from the LM?
I like to limiting or completely shutting down the power output. For example in case of a dynamic energy contract in periods with a negative energy price.

Thanks, that works great for me. But now i have all readable values from the inverter. I like to control the output from the inverter as described in:
photovoltaikforum.com/core/attachment/88445-power-control-open-protocol-for-solaredge-inverters-pdf/
Question 1: On Page 3 i see some info, but don't know how to start.
Register 61442, 61443, 61762 and 61700 doesn't return any value.
Question 2: Is there an easy way to display the returned values as readable text?
Code:
require('luamodbus')
mb = luamodbus.tcp()
mb:open('x.x.x.x', 1502)
res, err = mb:connect()
if res then
log("connected!")
mb:setslave(1)
r0 = mb:readregisters(40069) -- 101 = single phase, 102 = split phase, 103 = three phase
r1 = mb:readregisters(61440) -- RRCR State
r2 = mb:readregisters(61441) -- Active Power Limit
r3a = mb:readregisters(61442) -- CosPhi 1/2
r3b = mb:readregisters(61443) -- CosPhi 2/2
log(r1, r2, r3a, r3b)
--To enable the dynamic power control mode, set the following:
-- AdvancedPwrControlEn on address 0xF142 to 1 (enable). It is disabled (0) by default. -1.0 - 1.0 (61762)
-- ReactivePwrConfig on address 0xF104 to 4 (RRCR mode). It is set by default to 0 (Fixed CosPhi mode). (61700)
-- Issue a Commit Power Control Settings command on address 0xF100 in order to make this setting effective. (61696)
r4 = mb:readregisters(61762) -- AdvancedPwrControlEn
r5 = mb:readregisters(61700) -- ReactivePwrConfig
r6 = mb:readregisters(61696) -- Commit Power
log(r4, r5, r6)
else
log('connect failed', err)
end

Try writing 1 to F142, log errors and then try sending a 50 to F001.

For Float32 values use:
Code:
cosphi = mb:readregistervalue(61442, 'float32', 'w')
log(cosphi)If the returned value is incorrect change the third parameter from w to n
Similarly for Int32 and UInt32 values change the second parameter to either int32 or uint32

Code:
log( mb:writeregisters(61762,1) )
log( mb:writeregisters(61696,50) )twice times in the log:
* arg: 1
* nil
* arg: 2
* string: Operation timed out

Thanks it works great!
log( mb:writeregisters(61441,100) ) --F001 0-100
