February 9, 20233 yr Hello. I am about to install a 7.3kw east/west array. There will be an equal number of 8 panels on each side of a shed roof approx 15degree pitch. I am using a solid 6kw hybrid inverter. My question is about the wiring...Best to connect each side up in series but then connect both sides in parallel? There is no overhead shading. Thanks.
February 9, 20233 yr Check the inverter manual for minimum voltage per string. If it is a single string inverter (doubt it is) then it is the wrong sort for a split system.
February 9, 20233 yr Author It's a solis hybrid 6kw 5G inverter SOL-6K-RHI-48ES-5G-DC. 600vDC max per string...I can't see how many strings it can support although two connections on the base of the unit (2x DC positive and negative) for panel connections so I'd say 2 strings Edited February 9, 20233 yr by Huckleberrys

February 9, 20233 yr SOL-6K-RHI-48ES-5G-DC: MPPT: 2 according to here: https://www.zerohomebills.com/product/solis-rhi-6k-48es-5g-6kw-hybrid-solar-inverter/ MPPT 2 = 2 strings. Put east facing panels on one string and west on the other Edited February 9, 20233 yr by JamesPa
February 9, 20233 yr Author So wire each side in series and have each side as a string. Ideal. Thanks
