Maybe what I need to do is independently measure the current of each CT separately when not attached to the sol-ark and compare to the sum of the currents when both are connected to the sol-ark in parallel. If they are close, then I would think it is accurate enough. Otherwise, maybe they are...
Engineer775 showed a customer of his that stacked two of the EG4 6-battery racks - clamped them together with threaded rods - see
about the 8:00 minute mark.
Alternatively, you could go with a 48U rack solution similar to this...
With dual Sol-ark 15k install and 400a grid service, is it ok to parallel a pair of CTs (per leg) into the master inverter? In other words, my grid line has two 4/0 wires per leg going to the meter for 400a service. Can I put a CT around each of these wires and then parallel them together at the...
Dual Trace SW4024 (true sine wave) inverter power panel for sale. Includes 2 C40 PWM charge controllers (the display on one of these is flaky but the controller is functional), 250A DC battery breakers, 4 battery temp sensors (2x for C40s and 2x for the inverters) and built-in battery chargers...
400 amp service with 2 200a main panels. Will be installing 2 sol-ark15s and am thinking about omitting the transfer switch(es). Will still have the (400a) grid disconnect required by the utility. I understand lack of a transfer switch makes removing an inverter from service more time consuming...
Not really - it's slow going - I'm looking for new panels to go with the Victron eventually - the dual C40s can only handle 80*24V = 1.92kw - I'd like to charge the batteries faster...
I'm still using the dual Trace C40 controllers. My panels only supply about 1.6kw max and the controllers don't understand LFP batteries. I'm hoping to switch to a Victron BlueSolar 250/100 controller with a VE.direct port that will talk to the EG4-LL's via pylontech protocol...
I'm looking to replace some existing panels on a roof mount and because of space constraints need to get as close to 60" length as possible, so I'm looking for 60 cell panels. Since they're on a non-reflective roof, I'm not considering bifacial. Which panel would you recommend to fit these...
FWIW, My old dual stacked Trace 4024 power panel powered up with a set of EG4-LL batteries without issues. I had the inverter loads bypassed and it came up in the "off" state. Glad I ordered the LL's at this point after reading through this...
R&L delivered my EG4 batteries as well. One box was damaged - looked like it had gotten hit by a badly aimed pallet fork and there was 1 board broken on the pallet. I took a chance and accepted it. Turned out there was no battery damage - only a couple mounting ears were bent on 2 of the...
I just pre-ordered some 24V/200Ah EG4-LL batteries from Signature Solar to replace a flooded lead-acid battery bank. Looking forward to receiving them in another month or so.
I would like to connect these batteries to an old Trace SW4024 Dual Inverter Power Panel...
Thinking about the new Chargery P series BMS, but I haven't seen any spec sheet. For instance, does anyone know the active balancing current?
thanks!
