Pay attention to the installation process manual attention to safety matters, there are problems please contact the customer service mailbox.

During the mixing process, it is ensured that each panel has one S1, up to 3 S1s in series in the case of series connection, and that the power of each solar panel is less than 230W, on this basis, it can be connected in parallel, the specific upper limit depends on the battery current withstand limit.

Series ≤3 blocks (voltage limit) , parallel ≤12 blocks (current limit) .

Anti-shadow technology ensures efficient power generation. Traditional system veneer shading leads to overall efficiency degradation; whereas SolexBrick S1 optimizes independently for each board, maintaining 100% output power for the other boards even with partial shading.

It will vary depending on the battery you are using.Can be estimated using the following formula.

Formula:Battery Capacity(X wh=VxAh)/Input Power(W)x 1.2 or more for buffer e.g. If the output of Solarbag 400 is around 380, a 12.8V 100AH battery(1280AH）can be fully charged in 1280/380 = 3.3 hours. Due to the weather may it be longer like 3.3 hour x 1.2=4hours.

Normally a 100Ah battery can be fully charged half day. And in good weather the OptiSolex 400W Portable SolarBag can help you to charge 200Ah 12V Battery for daily use.

Operating temperature range: -40 °Fー149 °F Heavy rain/dust is still working normally.

2.What You’ll Need

Water (preferably soft or purified to avoid mineral stains)

Soft brush, sponge, or microfiber cloth (no harsh materials like steel wool)

Mild soap or solar panel cleaner (avoid strong chemicals or abrasive cleaners)

Hose or low-pressure spray (no high-pressure washers, which can damage panels)

3.How to Clean

• Step 1: Rinse with water to remove loose dirt.
• Step 2: Gently scrub with a soft brush/sponge and soapy water for stubborn grime (like bird droppings)
• Step 3: Rinse again to remove soap residue.Step
• Let it air dry or wipe with a clean cloth (avoid leaving water spots)

4.Safety Tips

Don’t walk hard on panels—they can crack! Use a long-handled tool if neededAvoid extreme weather (high winds, rain, or snow) while cleaning.

5. How Often?

Every 2-6 months, depending on dust, pollen, or bird activity in your area.

If Your Solar Equipment (IP67/IP68) Gets Flooded:Turn Off Power – Shut down the system immediately to prevent electrical hazards.Check the IP Rating.

IPX4 (Junction box of Solarbag): Can handle splashes (like rain), but NOT submersion or high-pressure water.

IPX7（200W mountable solar panel）: Can handle temporary submersion.

IPX8 (S1): Can withstand deeper/longer submersion.

Dry It Out:Unplug and remove excess water.Let it air-dry completely (24-48 hours) or use silica gel packs.Do not use heat (like a hairdryer), as it may damage seals.

Inspect for Damage:Look for cracks, corrosion, or water inside.Test functionality before reconnecting.Consult a Professional – If unsure, contact the manufacturer or a solar technician
