- Inverters that support high voltage (500v) storage batteries
There are of course plug and play options, like the Pylontech H1 or BYD HVL that meet UL9540 In my case, I'm running the Seplos HItens ( pair in parallel for 40kwh ) just received with are half the cost of the UL9540 options The Hitens for the Solis S6 come in 10kwh, 15kwh and 20kwh options
- REPT, EVE or CATL? | DIY Solar Power Forum
I'm looking for 15 or 30 kWh storage Current offer is for REPT 280Ah, EVE 304Ah and CATL 302Ah Can you, please, share some quick feedback on the different
- Need help info about CAN protocol from HV battery systems which . . .
I asked BYD and Pylon for the CAN HV protocol data No positive response Also i asked Deye about this My request needs to be approved (sigh) I’ve got a general document which i think Deye uses, but i can’t get it working The inverter does not recognize the data, maybe due to the fact i don't know if i implemented it correctly, and
- Can communication SMA to BYD HVS HVM | DIY Solar Power Forum
Can't directly help with HV, but I have data for BYD B-Box CAN to a GoodWe inverter (set to BYD comms) Status flags in 0x35A seem to be the same as SMA SunnyBoy So it's much the same as described by SMA without 0x35B and with 0x308 as an inverter heartbeat message

- YamBMS JK-BMS-CAN with new Cut-Off Charging Logic (open-source)
I understand that communication between the BMU and your two battery packs takes place over an RS485 bus with an unknown BYD protocol We could remove the BMU and connect everything to YamBMS (if the BYD RS485 protocol document is easily found) YamBMS is, in a way, a BMU Keep the BMU and connect it to YamBMS via a CAN bus input
- Dyi battery to fronius hybrid inverter | DIY Solar Power Forum
At the moment the only officially compatible battery is the BYD Battery-Box Premium HVS HVM, which range from 5 to 22kWh Power output depends on the battery size chosen, as operating voltage varies Last edited: Jun 6, 2021
- Best used ev battery 2025 (almost) for diy battery bank.
As for BYD, the 60 kwh battery is certainly LFP But it comes in 126s1p form factor, using "blade" LFP cells (prismatic, but thin and very long) There are no "modules" in the BYD Blade LFP battery So while technically you can separate the cells, 126 doesn't divide equally to 16s or 15s packs, so you will waste some cells
