I did find slo blo (tube type) fuses, so if I can use them, that's better Yes?? But a regular 5a for the Solix 12 and a 7.5a for the 15, will work, Yes? Do you recommend putting them closer to the unit or to the battery? Sorry for all the questions but I'm just trying to do this as right as I can. Really appreciate you guys and this site.
