What i have to do is to create a code in a plc (modicon m340) where i can control the system and maximise a self consumption, the priority is to take from the PV, and not from the grid, send the surplus to the battery if its SOC is low, not feeding into grid unless if we have critical cases (like when the battery is full, and no loads are applied, in this case we can feed in the production of the pv into grid), the communaction with the victron and plc is via modbus TCP/ip I'm working on a victron system connected too 2 sources of energy (Grid and PV, NOTE : the 2 inverter are not interfaced together, they are independant ) so i have a : Thank you! puitl asked Mar 29 at 12:53 PMĭaniël Boekel (Victron Energy Staff) commented I think this function would be perfect :) When discharging the state is switching into bulk and the game starts over :) (the same like with the DVCC-function "max. I have seen in the VRM that the "VE.Bus state " is also switching from bulk to absorption when the CVL is reached, therefore i have the wish for you to add following "DVCC-float voltage" function:Īctivating the new switch "Individual float-voltage" is showing the following two adjustable parameters:Īfter one to seven hours (adjustable) staying in absorption, DVCC pretends the set float voltage as new CVL > only when BMS-CVL is higher of course
I have a Seplos-BMS for example which only has a fix CVL, so the battery always stays at the absorption voltage which is not very gentle. Loading to the absorption-voltage and after that switching to float-voltage is a really useful function from you : At first higher voltage for fast charging and top-balancing and after that switching to the gentle float-voltage. Hi my dear Boekel (Victron Energy Staff) it´s me again :) My alternative is the cost and effort to have the EasySolar moved to another room, with the lengthening of the wires. I guess replacing these fans myself will affect the warranty? Replacement Fan: I need some advice - I read here than some has replaced the fans with the a Noctua equivalent, which has much as lower noise spec? Was it worth the effort? It is not bearing noise, just the fan air noise. I have not yet opened the enclosure to understand why it makes such a noise. The current fan JF1238B2HR-R, gives a spec of 43.5dB, which means the position of fans in the blue enclosure is the reason for the noise.

60dB (fans at full speed)Ĥ - Outside the encl. With an uncalibrated phone based noise meter, the EasySolar sound measurements are:Ģ - At m y workspace - 50dB (EasySolar fans at full speed)ģ - 1m from blue encl. It fans, from day one, are extremely noisy. I have an EasySolar 48V 5000VA, installed 30 days ago.
Is there a way to check this (other than running VEConfigure and looking at the Assistant tab, because it is present there.)Īny help would be very much appreciated! Links to other documentation on the MK2 MK3 protocol would be very nice too.
What am i doing wrong? It looks like I don't have the Assistant in the RAM table. Sending the CommandWriteData does not make any sense now. This response indicates a Unrecognised Command. The documentation states that there should be no response. When i do that by sending I get a response of The document explains that one should first read the Assistant ID and table size in the RAM ID table by reading RAM ID 128. I am trying to implement the example of paragraph 3.6.4 from the document
