Understanding what electronics can the BougeRV 200W energy up will depend on your photo voltaic panel setup and location. 

As a standalone, a 200W photo voltaic panel is finest for powering smaller gadgets like cell telephones, LED lights, and laptops. Nonetheless, common patrons of Climatebiz know that this setup might be enhanced with a photo voltaic charger, battery for vitality storage, and an inverter to transform 12VDC to 120VAC (see photos beneath).

We used two (2) 12V 12Ah lead acid batteries and a 12.8V 10Ah LifePO4 battery. We consider they’re one of the best ways to show the way to make the most of a photo voltaic panel with out blowing our funds.

Within the pattern software proven beneath, we tried plugging in a laptop computer charger rated at 65W together with an Airpod and an iPad drawing 15W every (5V @ 3A). 95W is drawn from the solar-charged battery by way of a 500W inverter.

Sensible Utility of BougeRV 200W 9BB Photo voltaic Panel

So how did we cost the 144Wh lead acid battery utilizing the BougeRV 200W 9BB photo voltaic panel? Let’s break down the method by wanting on the parts.

We already mentioned important photo voltaic system parts in our articles about off-grid cabins and RV photo voltaic techniques, however let’s recap: photo voltaic panels, batteries, inverters, cost controllers, cables, terminals, multimeters, and instruments are the important photo voltaic system parts.

1. Photo voltaic Panel (BougeRV 200W 9BB)

2. Cost Controller (30A PWM Cost Controller)

Cost controllers act as protecting gadgets between the photo voltaic panel and the battery. Primarily based on the voltage and present output of the BougeRV 200W 9BBpanel (17.98V and 11.12A at most output), we determined to go together with a Renogy 30A PWM Cost Controller.

For those who’re questioning why we selected a 30A PWM Cost Controller to reasonable a 200W panel producing 11.12A at max energy, we agree it’s slight overkill. However permit us to clarify our reasoning.

Our 30A 12V/24 PWM Photo voltaic Cost Controller

Our predominant standards for going with this product are:

• Funds — not sufficient for an MPPT controller (see PWM vs. MPPT);
• Security — cost controllers act as security gadgets so long as their specs can deal with the present enter (in our case, 30A>>11.12A); and
• Status — Renogy is a trusted model for PV tools and has a superb observe file of post-purchase help;

3. Battery (Lead Acid and LifePO4)

A cost controller received’t perform if it doesn’t have a battery to guard it. We additionally know that batteries aid you retailer photo voltaic vitality for later use. Nonetheless, they’re costly to personal.

For the sake of this demonstration, we acquired entry-level batteries rated at 12V / 10Ah to 12Ah.

If you’re on the lookout for heavy-duty batteries, we recommend getting 100Ah as much as 200Ah batteries rated at 12V or 24V, relying in your system.

4. Inverter (500W Inverter)

Inverters permit your electronics to obtain 110V to 240V AC from a DC supply reminiscent of photo voltaic panels or batteries (see picture beneath).

A 500W inverter is sufficient to energy important digital tools. Nonetheless, extra critical home equipment reminiscent of microwaves, toasters, espresso makers, and air fryers require extra in depth scores and cleaner AC sine waves. We advocate 2000W to 3000W Pure Sine Wave AC inverters for these purposes.

Recommendation: though this demonstration’s 10Ah or 12Ah battery can present 500W to 3000W of energy, it may solely achieve this for a brief interval contemplating the depth of discharge and vitality storage capability limits.

Actionable Recommendation: research your energy and vitality necessities when designing your photo voltaic system.

5. Instruments and Cables

After all, additionally, you will want some instruments and further equipment to finish your setup.

Right here is our guidelines for this BougeRV demonstration:

Theoretical Planning for Photo voltaic System Setup

Let’s have a look at the best BougeRV setup utilizing our evaluation:

The BougeRV 200W 9BB Photo voltaic Panel produces 17.98V and 11.12A at peak energy.

Batteries are generally rated between 12V and 24V and have a day by day cost/discharge cycle for hybrid grid-tied residential purposes. Due to this fact, we desire getting an MPPT cost controller, which is extra environment friendly than the PWM.

MPPT vs. PWM Comparability for BougeRV 200W 9BB Panel

So right here is our thought course of: the photo voltaic panel produces 17.98V and 11.12A whereas our battery is rated 12V and may deal with as much as 14V.

PWM Photo voltaic Cost Controller

If we use the PWM photo voltaic charger, it will cut back the photo voltaic panel output to 14V; subsequently, it’ll get

14V x 11.12A = 155.68W of most energy to cost the battery.

MPPT Photo voltaic Cost Controller

Then again, the MPPT photo voltaic charger will take the total output of the BougeRV 200W 9BB photo voltaic panel (17.98V) after which converts it down (DC-DC) to match the voltage of the battery whereas sustaining the rated energy output.

14V x 14.29A=200W of most energy to cost the battery.

That’s 28.5% extra energy from the MPPT than the PWM! However that assumes the battery we purchased can take 11.12A to 14.29A of present.

What We Did

We purchased two (2) 12V 12Ah lead batteries for our demonstration that may deal with 3.6A of steady present. We related each parallel to the cost controller, rising the battery present capability to 7.2A.

We additionally used one 12V 10Ah LifePO4 battery with a 10A steady enter present ranking in its place take a look at.

Utilizing the PWM cost controller, right here is the theoretical operation of the entry-level system we made:

• BougeRV 200W 9BB: 17.98V and 11.12A
• PWM Charger Controller: Limits voltages round 12V or 24V and has a 30A restrict
• Lead in its place take a look at Acid Battery Setup: 12V to 14.5V and seven.2A

Anticipated Most Energy Drawn: 14.5V x 7.2A = 104.4W

LifePO4 Battery Setup: 12.8V to 14.5V and 10A

Anticipated Most Energy Drawn: 14.5V x 10A = 145W

Outcomes

We acquired these outcomes on a sunny day in San Jose, California. Clear skies, no clouds throughout peak hours.

Lead Acid Batteries In Parallel

LifePO4 Battery

The 12V system with LifePO4 battery shops 107W to 145W throughout peak hours.

One factor we observed through the information gathering course of is that the “PV Display screen” interface of the app at all times appears to observe the restrict of the battery.

This makes us wonder if these information are the precise output of the photo voltaic panel or if the cost controller is suppressing the photo voltaic panel output. However there’s a method to confirm if the BougeRV photo voltaic panel is working appropriately.

Utilizing PV Panel Assessments (V_OC & I_SC)

The Open Circuit Voltage (VOC) take a look at and Brief Circuit Present (ISC) take a look at are normal testing procedures to assist confirm the efficiency of photo voltaic panels. You’ll want a multimeter to conduct these exams; ideally, you wish to see VOC and ISC values close to the product specs.

For the case of the BougeRV 200W 9BB photo voltaic panel, the VOC and ISC are 21.62V and 12.09A, respectively.

To hold out the exams, you might want to:

• Have the photo voltaic panel face the solar
• Disconnect the photo voltaic panel utterly
• Measure the DC voltage between the constructive and detrimental terminals utilizing a multimeter
• Measure the present of the photo voltaic panel too.

Given the outcomes of the VOC and ISC exams, we are able to conclude that the photo voltaic panel is in good situation.

Certain it didn’t meet the precise values, however we expect it’s because we don’t meet some, if not most, of the photo voltaic panel Preferrred Normal Testing Situations.
