Bluetti SP350 350W Solar Panel

I bought the Bluetti SP350 to recharge my Bluetti AC300 + B300 and Bluetti EB150 Power Systems for both pleasure and emergency use. I had perviously used a mix of solar panels joined together but the output was sketchy due to different voltages, ages, and outputs. Having the SP350 solved these issues in a simple and easy to use way. The connectors on the SP350 are standard MC4 connectors and connect quickly and easily to the same matching connectors on both Power Systems. I also bought a 10 gauge DC extension cord with MC4 connectors to allow the remote use of the new panels. Even under non ideal conditions of cloud cover and non ideal sun angles, I managed to get up to 250 to 300 watts of output. This was more than enough to recharge. I even tried the SP350 inside my house near a window out of direct sunlight to recharge an AGM battery thru a charge controller. The new SP350 is portable and easy to set up. It is well made and speaks of quality. I am more than pleased to make it part of my emergency power planning.

It keeps my 200 AH of Renogy lithium fully charged, but takes up very little space. I may add a second one, but so far I don’t need it. One stays ahead of my power consumption.

This is the third time I have purchased these solar panels to go with the two I have already had in service and I like everything about them. They are ridged so they can hold up in low wind conditions with the back support system or you can hang them on the side of your camper, vehicle or house because of tie down gromets that are provided at both ends. They fold up very nicely into their own handled carrying case. They are easy to adjust if you are like me and try to follow the sun a few times a day to obtain the best charging. They work best in series (instead of parallel) with the Bluetti AC200P. I haven't found a down side to them yet, but will come back and update my comments at a later date if I do find a downside with them.

I love it

I was reluctant to buy it used but it came in excellent condition. I hooked it up to the EB70S and it started charging 145 watts on partly cloudy skies. Easy to take any where. Weight off my shoulders knowing we have power for home and camping.

Use this to charge up my bluetti solar generator and charges super fast. Together I can stay out off grid for weeks at a time and keep all the appliances working with energy to spare.

Have 2 of these. Still charges with clouds. Folds up to 20x20 case.

Arrived on time, was well packaged. Looks very well designed, making it easy to carry, easy to store, and easy to use.

Not the least expensive, but it works as advertised. Used them in Sedona and the red clay collected on the panels and was hard to get off.
