If so, what is the maximum number of panels I can connect in series?** A: The maximum number depends on your solar charger. It will list a maximum voltage. Look at the specs and see what the open circuit voltage of the panel is. Then look at your battery charger for the max solar input voltage. It can range quite a bit, so it is very important. Divide the maximum voltage for the charger by the open circuit voltage of the panel. The whole number will be the max number of panels. For instance - If the max input for the charger is 150V and the panel will output 52V open circuit, 150/52 = 2.88. The maximum series panels would be 2. 2 x 52 - 104. As long as that number is at least 20V higher than your battery voltage, you should be golden. Also, look at the short circuit amps to make sure you are under the max current for the charger if you hook your panels in parallel. Series panels add voltage. Parallel panels add current. **Q: Can this do a parallel or serial connection with the ecoflow solar panels?** A: The working voltage of this solar panel is 18V, which is suitable for your power station. The parallel voltage is unchanged, and the MC4 parallel connector is required. The series voltages are added. **Q: What's the average power output? Seeing most people post between 78-100w. My battery can take up to 200w, wondering if I can hook up 2 of these?** A: I’ve gotten between 102-95 on mine and yes you can connect two. You would need to buy a Y connecter set. **Q: Will this work with an ebl 300 watt?** A: The working voltage of the solar panel is 18V, if the power station accepts 18V solar charging, it will be adapted. ## Frequently Bought Together - ALLPOWERS SP029 140W Portable Solar Panel Charger for Laptop Cellphone, Waterproof IP65 Foldable Solar Panel with 5 Output, for Solar Generator, Power Bank, 12V Car Battery - ALLPOWERS Portable Power Station 300W (Peak 500W), 288Wh Backup Battery Power Supply with Pure Sine Wave 110V AC Outlets, Portable Solar Generator for Home Use Outdoor Camping Travel RV Emergency --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/283392741-allpowers-sp029-140w-portable-solar-panel-charger-for-laptop-cellphone](https://www.desertcart.jp/products/283392741-allpowers-sp029-140w-portable-solar-panel-charger-for-laptop-cellphone) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-07*
