Controller error code said low battery voltage (Lfp) tried to upgrade wire gauge in battery circuit to 10awg but the dc input connector I use for battery only seems to come in 12 awg is there a limit on 5.5x2.1mm dc input current around that wire gauge cutoff? Will I just need to get a new battery or smaller amperage solar controller? I have tried adjusting charging voltage on controller with no luck. Noone manufactured the cable I need 5.5mmx2.1 dc input to 10 awg
Any suggestions would be appreciated the system is a 200w solar panel to 30a solar controller to 512wh lfp anker powerstation
 
What controller? If it's the older metal case PowMr's or MakeBlueSky's there should be 2 terminals for each battery leg so you can run 2 wires and split the load.

The 5.5mm jacks are only designed for 10a on paper, there should be screw terminals on the bottom for real wire and just lose the jack.
 
Absolutely total WAGs
1.Get a solar generator with mppt solar input and plug in panels direct.
2. Or get a SCC with a DC output. Sunflower MPPT 30 amp
3. MAYBE get a cigarette plug and connect to the battery connections on the SCC and plug into the 12 cigarette outlet on the Anker.
 
WAGs? what is that? from what i read most if not all scc output dc the cigarette outlet is for battery output
 
WAG...wild ass guess. Or more precise..SWAG... scientific wild ass guess.
Your SCC has a battery hookup output point +,-. Connect the cig plug power cord there and plug the connector into the 12v outlet on the Anker. Make sure politary is correct on the 12v plug.
 
the cig charger goes into the same 5.5x2.1mm dc jack im thinking you mean to put the cig charger as an input which im not sure accepts input power if i cut the end off the dc jack side and ran wires into solar controller and other end being the cig charger on the battery is that what you mean?

The DC input on the powerstation is used for DC power or solar panel, 11 to 28 volts, 120 watts, 10 amps. Connect your panel directly not via a external controller.
The unit has an internal controller that accepts panel directly.

seems dangerous but yeah within the specs i just assumed id need a controller guess ill just run it straight from solar switch to powerstation ill put results up probably tomorrow if you dont hear from me its cuz my house burnt down in an unrelated electrical fire
