Review: Reliable Solar Power System - I wanted to help my sister after Hurricane Maria. It has been over 6 months that she has not had power. I put together a system that I could order from desertcart and send most of the components to Puerto Rico directly. I ordered the SolarEpic 40A MPPT Solar Charge Controller, four Uni-Solar PVL-136 PowerBond PVL 136 Watt Flexible Solar Panels, a POTEK 2000W Power Inverter Three AC Outlets 12V DC to 110V AC and the miscellaneous cables and fuses. I prewired the controller and the inverter and wrote a detailed set of instructions on how to connect everything else. Luckily, I found in PR the batteries at Batteries Plus, and I ended up using two 12 vdc 155 Amp-hours for the project. My sister and my nephew installed the system 03/03/2018 and it has been powering her fridge, a few LED lights, a fan and charging phones and computers since with no problems. These products are outstanding and provide very impressive performance.
Review: plug and play, works great. - I bought one of these for a solar setup in my cab over camper. It was basically plug and play with a lead acid battery and I've had zero issues with it this fall. When I first hooked it up, I had the polarity wrong from the solar panels. The unit didn't give a useful error message or anything, just showed no solar power, but mainly it protected itself and I was able to root-cause the problem. It has a nice timer feature that lets you auto-run a fan or whatever on a schedule if you want to move air through your camper each day.

## Questions & Answers

**Q: Newbie here... i have 8 100w panels, a solarepic 4210a, and 4 100 ah gel cell batteries. prefer 12v battery bank to match 12vdc loads. thoughts?**
A: Typical 100w 12 volt panels will have a max current rating of around 6 amps. You cannot put them all in parallel as the max current would be 48 amps which is greater than 40 amps the controller supports. Wire up two panels in series. Do this 4 times. Then wire the 4 pairs in parallel. This will be running at 48/2 = 24 amps and at a nominal voltage of 24 volts. Wire this to the controller PV input. Wire all 4 batteries in parallel so nominal battery voltage is 12 volts. Hook the 12 volt battery bank to the controller. It is fine that the PVs are at nominal 24V but battery bank at nominal 12V. They don’t need to be the same. You could even do 48V nominal PVs into the controller which would be running at max amps of 12 amps. However 24V nominal PVs will be more efficient per the controllers instruction booklet. Note that nominal PV voltage is not actual PV voltage. 24V nominal PVs will run between 24 and 40 volts or so depending on sunlight. But max amps will always be below the short circuit amps shown on the back of the PV. Hope this helps.

**Q: Does this unit have a 4 stage charger (bulk, acceptance, maintenance and equilization?**
A: Yes. If the battery voltage is below the set point, it will charge in MPPT mode at the maximum current it can supply. It does do periodic maintenance and equalization. When not doing any of these things, it will float charge the battery. It will always kick into MPPT mode where needed to supply power to a load.

**Q: Can you use more than one of these in parallel?**
A: I honestly don't know the answer to that as I've only used one at a time fed from two solar panels in parallel.  That's (1) MPPT fed by (2) 250 WATT solar panels.  I will tell you that I had one of these go bad on me while camping in my RV.  It developed an internal short while charging (2) 6 volt batteries connected in series.  Now the batteries were discharged pretty low after a previous day of rain followed by night.  The next day was very sunny and this probably created quite a load on the MPPT.  I replaced the fuses in it (both 40 Amp) and as soon as I connected the battery back up it blew both fuses again.  So this tells me that this thing should be fused for something less than 40 Amps (in my humble opinion).  If I was going to try what you are suggesting, I would make sure to fuse the BATT and LOAD sides for no more than 30 Amps each (but no more than 40 Amps total).  And I would also ensure to use all of the same type solar panels.  And all panels should have the same sun exposure.  Otherwise I think you are setting yourself up for a cascading failure effect!

**Q: What is the maximum wire gauge the terminals accept?**
A: It can handle max 6AWG cable.

### ⭐⭐⭐⭐⭐ Excellent Quality for the price!
*by A***R on October 19, 2018*

This MPPT Charge controller seems to be working quite well. I am running 250 watts of solar panels through it to two 100ah Deep-Cycle AGM batteries. This is day 3 and even on cloudy days (here in NW Washington State), my batteries have never dipped below 12.6. And I watch 24 inch smart tv with 50 watt speakers, a small led light, and a small fan. I keep a fan on all night to help me sleep. I am really glad I bought this charge controller and and happy to give it a 5 star rating.
